IQ Modulator Calibration

(E8267D Only)

This adjustment is used to transfer factory calibration data to the instrument.

During factory testing of the 3-20 GHz IQ Modulator, calibration data is stored on an EEPROM located on the 3-20 GHz IQ Modulator. This adjustment transfers the prelevel bias, mixer gain, and digital gain data from the 3-20 GHz IQ Modulator EEPROM to the instrument files.

Connections and Setup Procedures

1. Connect a GPIB cable between the controller and the signal generator being calibrated.

2. While performing this adjustment, follow all instructions on the controller display.

In Case of Difficulty

If this adjustment fails, perform the following steps in order:

1. Verify that the GPIB cable is connected between the controller and the signal generator being calibrated and rerun the adjustment.

2. 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.

3. If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
