Installing the License in an ESG Signal Generator Before installing the license file, save a backup copy in a safe place. To enable your ESG signal generator to play waveforms generated by the Signal Studio software, you must install a license file in the signal generator. Agilent sends you the license file by email when you redeem your license. To install the license file in your signal generator, follow the instructions below. Using Agilent License Manager The Agilent License Manager software requires a LAN connection between the PC on which it is installed and the ESG signal generator. If your equipment cannot be connected through a LAN, install the license using a GPIB connection and SCPI commands as described on page 4. 1. If you do not have Agilent License Manager installed on your PC, you can download it at no charge from the following website: http://www.agilent.com/find/licensemanager. 2. Establish a LAN connection between the PC running the Agilent License Manager software and the ESG signal generator as described in Equipment Setup and Connection in the Signal Studio online documentation. 3. Copy the license file to your PC. The license file has a.lic extension, and is attached to the email message you received when you redeemed your license (see Getting a License in the Signal Studio online documentation). In this example, the license file E4438C-US70000174.lic is placed in a folder named E4438C. 1
4. Obtain the hostname or IP address of your signal generator. Press Utility > GPIB/RS-232 LAN > LAN Setup on the signal generator front panel. The hostname and IP address are displayed as shown below. 5. On your PC, start the Agilent License Manager software. Click Start > All Programs > Agilent License Manager > Agilent License Manager. 2
6. In the Agilent Licence Manager main window, click File > Connect... to open the Connect to Device dialog box. 7. In the Device Address field, enter either the hostname or the IP address of the signal generator obtained in Step 4. 8. Click OK. The instrument address and its installed licenses appear in the tree view (left pane). The right pane displays additional information for each license. 3
9. Click File > Install License(s)... to open the Install License File(s) dialog box. 10. Use the Install License File(s) dialog box to navigate to the location where you placed the license file (*.lic) in Step 3. 11. Select the desired license file and click Open. 12. Wait for a message to appear, informing you that the license has been successfully installed in the signal generator. Refer to the Agilent License Manager online help for more information about using the software. 4
Using GPIB and SCPI Commands If you are unable to establish a LAN connection between your PC and your ESG signal generator, you can manually install the license using a GPIB or RS-232 connection and the Agilent Connection Expert software (or another command line tool). This method can be used for permanent and time-based licenses only. To install or move a transportable license, you must use the Agilent License Manager software on a PC connected to your ESG through a LAN as described in the previous section. 1. Copy the license file to your PC. The license file is attached to the email message you received when you redeemed your license (see Getting a License in the Signal Studio online documentation). 2. On your PC, start the Agilent Connection Expert software. Click Start > All Programs > Agilent IO Libraries Suite > Agilent Connection Expert. If you do not have Agilent IO Libraries Suite installed on your PC, you can download it from the following website: http://www.agilent.com/find/iolib. If you are not using Agilent Connection Expert, start your command line tool and proceed to step 6. 3. In the Instrument IO on this PC tree view, select the E4438C ESG signal generator connected via GPIB. 5
4. If the Task Guide view is not displayed, select View > Task Guide. 5. In the Tasks for This Instrument column, click Send Commands to this Instrument to open the Agilent Interactive IO window. 6. Open the license file you copied to your PC in Step 1 using Microsoft Notepad, or a similar text editor that creates plain, ASCII text files. Do not use a word processor such as Microsoft Word. 7. Using the text editor, select and copy the license file text. 6
8. Type the following SCPI command into the Command: field in the Agilent Interactive IO window, pasting the license file text you copied in Step 7 at the <license_line> location in the command. :SYST:LIC:INST <license_line> 9. Click the Send Command button to send the command, or the Send & Read button to send the command and read the response in the Instrument Session History displayed at the bottom of the window. 7
