7 PC-Gentec-EO User s Manual Revision PC-GENTEC-EO 1.1 Introduction The PC-Gentec-EO features a simple and intuitive software to watch and to control the readings from a Gentec-EO device. The PC-Gentec-EO supports the INTEGRA and the MAESTRO. For a current MAESTRO user, it will be very easy to find every option available and to navigate within the new software to obtain the correct measurement. For a new user, it will also be easy to find his way in the software since it is designed to fit Microsoft s new user interface standards.

10 PC-Gentec-EO User s Manual Revision QUICK START PROCEDURE 1. Install the PC-Gentec-EO software on a PC. 2. Install the power or energy detector head on its optical stand. 3. For a monitor, connect the detector head by sliding the connector latch to the right to unlock the connector. 4. Switch on the monitor if needed ; 5. Connect the Gentec-EO device to the PC with the appropriate USB cable. a. For MAESTRO, verify that it is not in SOLO2 Serial Compatibility or Binary Mode Measurement and that it is configured to use the USB port. (In the MAESTRO monitor, go to Home menu Set Device Serial Commands ) 6. Start the PC-Gentec-EO software. 7. Choose the appropriate graphic for your measurement: a. Real time with bar graph display b. Scope display c. Needle display d. Averaging display e. Histogram display f. Statistics display 8. Press the Connect button on the top left corner of the main window and change the measurement and display options in the appropriate tabs. a. Power heads will default to power measurement; energy heads will default to energy measurement. The display will default to a dual display in real time and scope (Fig 2-1) in auto range mode. b. Remove the head s protective cover and start the laser. Put the detector head into the laser beam path. Leave it there for a few minutes, until the detector has reached an equilibrium temperature. The entire laser beam must be within the sensor aperture. Do not exceed maximum specified densities, energies or powers. For the most accurate measurement, spread the beam across 60% to 80% of the sensor area. Attention: Power heads can be used with both CW and pulsed lasers. - Energy heads can only be used with pulsed lasers. Adjusting the zero (step 8a for power heads and 8b for photodiode heads) c. The power read by the PC-Gentec-EO when no laser beam is incident on the detector may not be exactly zero. For power measures, this is because the detector is not thermally stabilized OR there was a heat source in the field of view of the detector when you connected on the PC-Gentec-EO. As for photodiode measures, zeroing will remove the detector s offset.

11 PC-Gentec-EO User s Manual Revision Notes: i. Block off laser radiation to the detector. To reset the zero, wait until the reading has stabilized and click on the Set Zero in the Main Control Ribbon parameters menu. ii. If you have connected a photodiode, you must cover the diode and the zero has to be done for all scales. You will not have to do this manually for each scale as this is automatically done when you turn on the zero. In some software versions, a message appears requesting you to put the black cover over your photodiode. Touch the OK button after you have done so. The PC-Gentec-EO passes through all the scales to determine the zero diode for each scale. Refer to specific power detector documentation for complete installation and operating instructions. Power detectors are thermal sensors and are thus sensitive to temperature variations. For high-precision measurements, it is recommended to: Allow the power detector temperature to stabilize before zeroing the PC-Gentec-EO. Touch only the stand when handling the power detector. Do not touch the detector head. Do not zero adjust the energy detectors, such as the QE series. Avoid forced airflow or drafts around the detector.

There is no need to make a port selection, the PC-Gentec-EO will automatically find a connected Gentec-EO device or any available ports on the PC and will connect to it. Warning

14 PC-Gentec-EO User s Manual Revision CONTROLS menu If a USB Bluetooth adapter is present on a PC, it is possible that the connection will take longer. Some USB Bluetooth adapters use the same virtual port as the PC-Gentec-EO, but the delay for verifying the connection to the Bluetooth port is longer than the traditional serial port Turbo Mode button Fig. 3-5 CONTROLS menu The Turbo Mode is used for joulemeters to transfer data from the device. It switches the MAESTRO and the INTEGRA in binary mode to accelerate data transfer from the USB port. Turning off the Turbo Mode will put the device in ASCII mode. For optimal use, the Turbo Mode should always be on Set Zero button This button adjusts the zero on the detector head It resets the zero reading level. It does this by subtracting the power reading on the display as soon as the Set Zero button is touched. Subsequent measurements will be relative to this zero power level. The main purpose of this option is to remove reading offset caused by thermal noise in the environment. Thermal noise is caused by a detector that has not been thermally stabilized OR there was a heat source in the field of view of the detector when the PC-Gentec-EO was connected (for example, the hand or body of the user). Use this function once your power meter has achieved thermal equilibrium to ensure accurate measurements. For instructions on the proper way to adjust your detector s offset to zero see step 8 in Section 2 Quick start procedure. In Energy mode the zero clears the current value Start/Stop Acquisition button This button starts and stops the acquisition to a logging file. The different options for the acquisition can be made in the Set Acquisition tab. The Gentec-EO device must be connected to start the acquisition.

The filename for data logging, the file location and the option to add a timestamp to each value can also be set using this menu. Fig. 3-6 Acquisition settings options in Power mode

16 PC-Gentec-EO User s Manual Revision Set your Acquisition parameters in Energy Mode In Energy Mode, you can use the Set Acquisition tab to choose the sample rate and duration of an acquisition. The sample rate is defined to measure 1 pulse every X pulses (for example: 1 measurement every 10 pulses). The total duration is also set in a specified number of pulses. The filename for data logging, the file location and the option to add a timestamp to each value can also be set using this menu. Fig. 3-7 Acquisition settings options in Energy mode Warning The number of pulses acquired is the number of pulses that the PC- Gentec-EO received via the USB port. Depending on the device, this can be different from the number of pulses received by the monitor. Please refer to the specifications in section 1.2. For the MAESTRO, the repetition rate is limited to 500 Hz, the MAESTRO will perform a subsampling. If you need to make an acquisition using all the points measured by the MAESTRO, please use the MAESTRO monitor and store the file on a USB key.

19 PC-Gentec-EO User s Manual Revision GETTING STARTED 4.1 Connect your Gentec-EO device to the PC-Gentec-EO. 1. Connect your Gentec-EO device to the PC using a USB cable. 2. Install the PC-Gentec-EO on the PC. 3. If necessary, power up the Gentec-EO device 4. Start the PC-Gentec-EO 5. Click on the Connect button in the Main Controls ribbon. The software will scan each port on your computer and connect the PC-Gentec-EO to the first port connected to a Gentec-EO device. 4.2 To disconnect your Gentec-EO device Click on the Disconnect button in the main controls ribbon. 4.3 To change the measurement settings of your detector head To change the behavior of the detector head plugged into the Gentec-EO device, go to the Set Measure tab panel. Fig. 4-1 The Set Measure panel

20 PC-Gentec-EO User s Manual Revision Wavelength: Enter the desired wavelength. Press Enter or Tab to make the change effective. Range: Use the dropdown menu to select the desired range. The chosen value will be the maximum that the PC-Gentec-EO will measure before displaying OUT. By default, the Gentec-EO device is in Auto mode. Measure Mode: Use the dropdown menu to set the measurement mode (Power, Single Shot Energy, Moving Average, etc.). Please note that it can take up to 3 seconds for the PC- Gentec-EO to switch between measurement modes. Anticipation ON/OFF and Attenuator ON/OFF can be controlled in this menu. Corrections: Use these settings to set a multiplier and/or an offset to your measurement. The equation used is : Result = (Value*Multiplier)+Offset Trigger Level: Adjust the trigger level in 0.1% steps, from 0.1% to 99.9%. Trigger level is not available in power mode. External trigger option is not available in power mode and with Integra. Default value is 2% Wavelength The Wavelength menu is used to select the proper wavelength at which the detector is used. It applies a correction to adjust for the variation in responsivity at different wavelengths. Pre-programmed wavelength correction factors dedicated to each detector head are available and automatically loaded from the detector EEPROM, for version 5 and higher detector heads. When a new detector is plugged in, the calibration wavelength is the default selection. The PC-Gentec-EO automatically recognizes the latest energy and power detector for accurate autocalibration. More importantly, it takes advantage of our Personal Wavelength Correction : it reads the memory in the Smart Interface connector to provide a wavelength correction based on spectral data measured from that specific detector. Your measurements across the band have never been this precise or easy. The PC-Gentec-EO only allows you to choose values that fall within the detector s range. If you enter an invalid value, a menu pops up to signal the error and the PC-Gentec-EO automatically selects the default value, which is the wavelength used for calibration at Gentec-EO during manufacturing or subsequent service Range The Range is used to select the signal level read by a detector head. When a new head is plugged in, the auto mode is the default option. In this condition, the PC-Gentec-EO automatically selects the best range for the value being measured. You can also choose a fixed scale according to the specific connected detector head. The PC-Gentec-EO only shows range values that fall within the detector head s range. You can only choose from these available ranges When in a manually selected range, you should always use the next higher range to the measured value, for maximum precision.

21 PC-Gentec-EO User s Manual Revision Special care must be taken in the case of widely varying pulse energy to ensure that every pulse is detected. Contrary to the case of a power measurement where the auto mode adjusts continuously to the measured value, the auto mode in energy mode bases its range selection on the energy of the previous pulse. A pulse with energy less than 2% of the current scale will not be detected. Always set the scale to the best one available. To be sure to measure lower energies, set the scale manually to the lowest level and set the autoscale, the PC-Gentec-EO will autoscale to the best scale. In this case, the pulses that saturated the scale while the autoscale was searching for the best scale will be invalid Measure Mode Depending on the type of detector head connected on the Gentec-EO device, you can choose different measure modes. For thermopiles, you have the following measure modes: Power in Watts (default); Single Shot Energy in Joules 5 : (Energy mode/ calorimeter mode); Moving Average in Watts (Not available on this version, check our website for new versions. For photo detectors, you have the following measure modes: Power in Watts (default); Moving Average in Watts (Not available on this version, check our website for new versions Power in dbm (dbm = Log [power in Watts/0.001W]). For Pyroelectrics Energy in Joules (default); Average Power in Watts (Not available on this version, check our website for new versions). Energy Dose in Joules (Not available on this version, check our website for new versions); Moving Average in Joules (Not available on this version, check our website for new versions). 5 This function allows you to measure the energy contained in a laser pulse with a Gentec-EO power detector head. This mode of operation gives access to the same options as in the case of an energy pyroelectric joulemeter. The only restriction is that the time delay between pulses, Delay 1 Rep. Rate, must be compatible with the detector specification. (Please refer to the user manual for the specific power detector you are using.) You must select the range manually because the autoscale is deactivated when you select Energy Mode. Keep in mind that the power detectors are optimized to sustain high average power, not high peak energy. Always keep the energy density below the maximum energy density quoted in the manual for that specific detector. The energy mode is always available for power detectors with a typical sensitivity value. A precision of ±3% in the pulse energy measurement can be achieved if the power detector head is specifically calibrated in energy mode. Please contact your local Gentec-EO distributor or nearest Gentec-EO office for more information on obtaining a pulse energy measurement calibration.

22 PC-Gentec-EO User s Manual Revision Uncheck Anticipation to deactivate the power meter acceleration software that provides accelerated response. By using advanced algorithms and known properties of the detector, this software allows the PC-Gentec-EO to provide a very accurate power measurement a few seconds faster than the natural response of a thermopile power detector. It accelerates the natural response by a factor of 5 to 10. Turning off the anticipation will result in a slower response but will reduce the noise level and provide a more stable measured value in a noisy environment. Version 7 energy heads have been calibrated with and without the attenuator at a chosen wavelength. When enabling the attenuator, only the wavelength at which it has been calibrated will be available in the wavelength menu. Similarly photodiodes have been calibrated with and without the attenuator at chosen wavelengths. When enabling the attenuator the PC-Gentec-EO will prompt the wavelength menu because the available wavelengths with and without the attenuator are different. A checkmark shows when the anticipation or attenuator is activated. It is a toggle switch - select it to change between on and off. For the anticipation, the default is on and for the attenuator, the default is off Corrections The user can apply a multiplier and an offset value to the detector reading. Correction factors are most useful when sampling a percentage of a powerful laser beam or correcting for absorption along an optical chain. The default value for the multipliers is 1, and the default for the offset is 0. To activate the correction factors, click on the check box next to the multiplier and/or the offset The PC-Gentec-EO will then display the corrected value. For example, if you are measuring a laser beam passing through the 99.9% back reflector of a laser (giving 1/1000 th of the real value), choose Multiplier and enter 1000 in the dialog box. The PC-Gentec- EO will display the laser s power rather than the measured 0.1% sample on the main display. It is essential to make sure that the actual measured value also complies with the power and energy limits of the detector head. The auto range option is the default selection. You can select a specific range but it must always be based on the actual physical measured values and not on the corrected value. Of course, the displayed values and the display scale selection are then calculated to take into account the correction factors. Note that the Statistics are computed for the corrected values only Trigger Level The trigger level only functions if an energy detector head is connected or if a power detector head is used in Pulse Energy (Calorimeter) mode. This option allows you to change the Trigger Level from 2% of the full-scale default value. This proves to be especially useful in noisy environments. Acceptable values range from 0.1% to 99.9% with 0.1% steps. Caution should be taken when choosing a lower trigger level than the 2% default value in a high noise environment. The PC-Gentec-EO will not detect pulses with a value under the trigger level. Be careful to select a scale that is close to the measured value, if the trigger level is high. To reset the default value to 2.0%, simply click the Default button.

23 PC-Gentec-EO User s Manual Revision Caution! If you select a high value trigger level, the PC-Gentec-EO may not be able to detect all the values of widely varying energy levels in auto range mode. The auto range function uses the energy level of the last pulse to set the scale level. Therefore, it will not detect the next pulses if they are lower than the trigger level. As a result, the auto range may become caught on a high scale value. To avoid this problem, select a lower value for the trigger level, change the scale manually, or reset the auto range mode by reselecting auto in the Range menu (section4.3.2). Erratic triggering? In electrically noisy environments, it is possible that the PC-Gentec-EO will inadvertently trigger on the noise. If this is the case, increase the trigger level to 3% or higher if necessary. It is always good practice to reduce electrical noise generation or shield the detector and monitor when measuring very low pulse energies. You can also set the device to be triggered externally. Just click the External Trigger check box (not available on the Integra).

24 PC-Gentec-EO User s Manual Revision GRAPHICAL DISPLAYS The PC-Gentec-EO offers six different graphical displays to view and analyze your signal.

31 PC-Gentec-EO User s Manual Revision Averaging Averaging Display The averaging graph is the perfect tool to check laser stability over time. The averaging display is a bar graph that presents the statistics of a set of measures as a function of time. The PC-Gentec-EO measures a series of data during a user-defined period of time. Each bar represents the maximum, average, and minimum values of the measured data. The top of the white bar represents the minimum value while the top of the blue bar represents the maximum value. The yellow line represents the average value for each set of bars. This allows you to quickly evaluate the trends of the average, maximum, and minimum values in time. For Power Detectors: Fig Averaging display In the Averaging display mode, the power measurement is the average value defined in the averaging settings. For optimum averaging, when measuring the average power of a pulsing laser, it is preferable to use a sample period that is a multiple of your laser repetition rate. For instance, if you are running at 1 Hz, use an average period of 1, 2, 3 etc seconds. If it is at 1.5 Hz, use 3, 6, 9 etc seconds, as the sample period. Take note that if one data point is out of the current scale, the resulting period average will be OUT. You should set the scale higher than your maximum unfiltered measurement to avoid this situation. For Energy Detectors and Power Detectors in Energy Mode: In the Averaging display mode, the Energy measurement is the average value defined in the averaging settings.

32 PC-Gentec-EO User s Manual Revision Averaging Display Options Panel The options panel for the Averaging display allows to control the number of digits and to change the averaging period (the period of one bar on the graph).

34 PC-Gentec-EO User s Manual Revision Warning Statistics in PC-Gentec-EO are calculated from all the entry points coming from the serial port of the Gentec-EO device. Depending on the device, this can be different from the number of points received by the monitor. Please refer to the specifications in section 1.2. For MAESTRO users who want to accumulate statistics from all acquired points at rates greater than 500 Hz must use a monitor, such as a MAESTRO and use it statistics directly on a MAESTRO and store them to a USB key. The statistics available depend on the type of detector that is plugged, as can be seen in the pictures below. Tip Fig Statistics display in Power mode

Tip Fig Statistics display options panel in Energy mode Continuous and Fixed statistics duration mode In both statistics modes, the statistics start and reset with the Start Statistics button in the controls section of ribbon bar, or with the button at the top right corner in the statistics graph panel. The difference between the Fixed and the Continuous modes is that, in the Fixed mode, the statistics will stop automatically after the duration period. With the Continuous mode, the statistics, after the duration period has ended, will automatically reset and start again with the same duration period. This will continue until the stop button is pressed.

37 PC-Gentec-EO User s Manual Revision Tips If Save statistics to the acquisition file is checked, the Continuous mode cannot be used. The statistics are entered into a file at the end of the duration period, so we must use the Fixed duration. The file used for the statistics is the same as the file used for the acquisition. Therefore, if the filename of the statistics is changed, the acquisition log filename will be changed automatically. To store only the statistics in a file, check the Save statistics to the acquisition file and start the statistics. To add statistics at the end of an acquisition log file, check the Save statistics to the acquisition file option and start the acquisition. The statistics will automatically start at the same time and will be entered in the file at the end of the acquisition.

Please verify your connection. Try the following steps, in the order presented, until your connection is active. Make sure the USB driver is installed. Verify all your connections. Verify that a Gentec-EO device is powered on and connected to the PC with a USB cable. For a MAESTRO monitor, go to Home menu Set Device Serial Commands o Verify that the MAESTRO is not in Solo2 Serial Compatibility (ASCII Only) mode. o Verify that the MAESTRO is not in Binary Mode Measurement (Energy Mode only) mode. o Verify that USB (if a USB cable is used) or RS-232 (if a RS-232 cable is used) is selected o Restart the MAESTRO. Unplug the Gentec-EO device. Restart the PC-Gentec-EO. Restart your computer. If none of these steps have worked, contact Gentec-EO support at service@gentec-eo.com. 6.2 Moving Average mode is not working This is because this feature is not yet available. If the moving average is activated directly on the Gentec- EO device monitor, the PC-Gentec-EO will stop displaying measurements. 6.3 My settings won t load Settings can be saved exclusively for one type of detector head. If you have a power detector head and a photo detector head, you cannot directly load and apply to the photo detector head the settings from the power detector head. For each new head type, to avoid redoing all the manipulations by hand, follow this procedure: 1. Connect your first detector (ex: A photo detector) 2. Customize the PC-Gentec-EO to your wishes 3. Save the settings to a file using the Save Settings button in the CONTROLS menu (ex: Photodetector.geo ) 4. Disconnect your first detector 5. Connect your second detector (ex: A power detector) Note: All the settings from the first detector are still active 6. Verify the options in the Set Measure settings tab 7. Save the new settings to a file (ex: Power.geo ) After that, you can plug any of your different detectors and load the corresponding settings without problem.

39 PC-Gentec-EO User s Manual Revision Repetition Rate and Average Power are not displaying in the statistics mode These features are not available yet. 6.5 Traditional Communication Settings The traditional serial communication interface also allows you to operate the MAESTRO from a remote location. We recommend using the specific serial data acquisition software PCMAESTRO, if no automated acquisition is involved because it is much easier to use. In the case of automated measurement controlled by other software, use the following commands to control the MAESTRO. They are divided into two groups: The control commands allow you to change the MAESTRO s settings without using the MAESTRO s touch screen. Remote control commands do not yield any data, they only confirm that the command has been executed. The acquisition commands are used to obtain information on the current status of the MAESTRO. They do not change the MAESTRO s settings, they return the requested information. 7 SERIAL COMMAND FORMAT Serial Protocol Rules: Commands are sent as text strings. The response will either be data or an empty string Text mode rules: All text commands must begin with a trig character (*). You do not need to end with a line-feed, a carriage-return, or both. Parameters must NOT be separated by any spaces. Characters do not have to be capitals, mixed upper and lower case is ok. Replies to all text mode commands are also in text mode, and end with a carriage-return and line-feed. In case of an error, the reply string is in the following format: Error X: reason [enter] X is the error code, and reason is an explanation. See Error Codes at the end of this section. Because all Text Mode replies end with a carriage return <CR> or line-feed <LF> (or both), a text reply contains tabulations when many elements need to be separated in the string. This is useful when exporting data to a spreadsheet Binary Mode Description Description The MAESTRO AND INTEGRA has two Communication Modes: the Binary Mode for FAST data acquisition and the ASCII mode. Maestro: The resolution is 14 bits for both cases. Integra: The resolution is 12 bits for both cases in Joulemeter mode.

40 PC-Gentec-EO User s Manual Revision Only the Joulemeters support the binary mode. Thermopiles in energy mode, thermal heads in standard mode and photodiodes are coded in ASCII. To select the binary mode select Home/Set Device/Serial Commands/ Serial Binary Measurement. If you wish the MAESTRO to remember this setting, touch the Set as Default button. The value in binary mode is coded in two bytes. Binary Joulemeter MODE Byte #1 O Y X X X X X X Byte #2 O X X X X X X X B = The sign. Y = The MSB for the Wattmeter Mode. X = Bits of the Codification. FOR ALL MODES O = Order 0 = First byte (MSB) 1 = Second Byte Codification Example 1: Measurement in Joule = Current Scale *Value in Decimal/16382 For 151 mj on the 300 mj scale on Channel 1 The MAESTRO will send you: 40B6 HEX VALUE, where: 10 = The first second bit (0) is the order of the MSB is the MSB of the codification 9B = The first bit (1) is for the order so this is the LSB of the codification The Total Codification is , which is 8246 in decimal (8246/16382 * 300mW = mw) The codification = No connector The codification = OUT detected
