Post Repair Procedures
If a manual performance verification test fails:
1. Verify that the test setup is correct.
2. If the tests setups are correct, go to
Keysight X-Series Signal Generators Service Guide
— For I/Q Calibration and Self Tests
— Confirm that all external cables, including GPIB, LAN, and
USB cables, are disconnected from the signal generator.
— For Relative Frequency Range and Accuracy Verification
— Verify that the cables are connected correctly.
— Verify that the spectrum analyzer is set to external
reference.
— For Leveled Output Accuracy Verification
— Verify you are using the appropriate power sensor.
— Normally, power sensor calibration factors are
automatically downloaded to the power meter when the
power meter turns on. If this does not occur, manually
enter the correct calibration factors for the power sensor
you are using.
— Verify the power sensor is properly calibrated to the power
meter.
