7 4 Description Many professional laboratory instruments (e.g. scope, generator or voltmeter) can be controlled and readout via SCPI commands. Further some functions can only be accessed via the SCPI commands and not via the device operating panel. With the control panel stute.scpi you can easily control the measurement and read out the measured values, even in a loop. Very interesting is also the integration of audio files. With this capability you can measure frequency responses without a signal generator, e.g. to check a Bluetooth audio adapter. 5 SCPI overview 5.1 SCPI control modes Note: The SCPI control mode will be set due to the SCPI script file header. 1. Mode xy Application example: Frequency response or THD graph Output source: your lab instrument, controlled by SCPI Input: your lab. instrument y-axis: measurement value, x-axis: frequency (value from stute.scpi) Settings: 2 to 30 measurement points per decade between fmin and fmax 2. Mode yt Application example: data logger (y-t measurement), e.g. measure Vdc all 5 seconds Output source: n/a Input: your lab. instrument y-axis: measurement value, x-axis: time base Settings: loops, delay between two measurements seconds 3. Mode xy-f Application example: Frequency response or THD graph with an audio file Output source: audio file (mp3, wav ) from a file table about an PC audio interface or Bluetooth audio interface Input: your lab. Instrument, signal value and frequency y-axis: Measurement value, x-axis: frequency (instrument) Settings: audio file list Note: - The mode xy-f expected 2 measurement values The level and frequency Chapter: Description 7

11 6 SCPI syntax Note: You can create with each text editor a SCPI script file, e.g. like notepad from Windows. Store the file as a text file (*.TXT) 6.1 General Die SCPI command file is divided into: The header (first line) o First character is a! o Followed by the abbreviation for the SCPI mode XYI Mode xy YTT Mode yt XYF Mode xy-f The instrument setting (one time run) o A list (multiple lines) of SCPI commands to adjust the instrument, like Vdc or Vac measurement All lines will be transmitted via RS232 o Delimiter to the loop commands is the single char > in a separate line The char will not transmitted via RS232 The measurement loop o Multiple SCPI commands for the measurement in a loop Needed values for the SCPI command, like the output frequency, will be replaced by the wild card stute.scpi replace the wild card with the calculated frequency o All lines will be transmitted via RS Example SCPI Mode xy THD chart Description: Measure THD total plus k2, k3, k4, k5 as a chart in the frequency range from fmin to fmax. Note: fmin and fmax are settings from the stute.scpi user interface. Code example for Keithley 2015 THD.

The cursor can be set vertical (x) and horizontal (y) View and modify the cursor The cursor view is activated with a left-click at the XY diagram area. The cursor (a dotted line) is shown plus a new screen with the cursor measurements. The next left mouse click action defines the position for the cursor Pos. 1, e.g. to calculate later the difference between Cursor pos. 1 and 2. Move the mouse cursor to the next position. The second left-click set the cursor for Pos. 2, e.g. for a second frequency to view the damping between f2 and f1. The next click set the cursor for Pos. 1 at the new position and removes Pos. 2, and so on. You switch between the horizontal or vertical cursor about the x/y option. The rectangle Pos 1 and Pos 2 displays the values to the cursors. The differences are displays in the Delta rectangle. Pos. 1 Pos. 2 Cursor Chapter: Module XY screen 3 0
