E8257D/67D, E8663D PSG Signal Generators Service Guide
Post–Repair Procedures
CPU Configuration
4-14
CPU Configuration
1. Power on the signal generator.
• If the firmware loaded on the CPU matches the instrument model, go to Step 6.
• If the firmware is for a different instrument model, the instrument should still turn–on, but the firmware needs
to be changed. To change the firmware continue with Step 2.
2. Set the IP address:
Press
Utility > GPIB/RS–232 LAN > LAN Setup > IP Address.
a. Set the LAN configuration to DHCP.
b. Cycle the signal generator power.
3. Set the remote language:
•Press
Return > Remote Language > SCPI.
4. Check that the instrument identification number (IDN) is correct by executing the command, *IDN?.
• If the IDN is not correct, change the IDN by executing the following command:
:SYST:IDN "Agilent Technologies, <Model Number>, <Serial Number>, <Firmware Revision>"
NOTE When executing the command, ensure that the firmware revision parameter matches the signal generator
model. For example, E8257D and E8267D use firmware revisions that start with C.04.xx.
5. Download the new firmware:
a. Go to www/agilent.com/find/psg/upgradeassistant
b. Download (save to disk) both the PSG–ESG Upgrade Assistant software and the latest PSG firmware.
