This adjustment sets the signal generator to 20 GHz at +5 dBm and measures the +9 VDC supply on the A10 ALC assembly. This value is used by the I/Q Upconverter.
Connect a GPIB cable between the controller and the signal generator being calibrated.
While performing this adjustment, follow all instructions on the controller display.
If this adjustment fails, perform the following steps in order:
Verify that the GPIB cable is connected between the controller and the signal generator being calibrated and rerun the adjustment.
If this adjustment still fails after step 1, refer to the troubleshooting section of the signal generator's service guide. If you do not have a printed copy of the service guide (Option OBW), one is available either on the CD-ROM that came with your signal generator shipment or on the Keysight Website.
If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
