External Leveling

(E8257D Option H43 Only)

This test verifies that the signal generator is able to provide an externally leveled signal within a desired voltage range.

During this test, the signal generator is externally leveled using a negative crystal detector. The negative voltage from the crystal detector is measured with a digital voltmeter in order to verify that the signal generator's output power is able to be leveled within the desired functional level. If an unleveled condition exists prior to achieving the functional voltage level, the test fails.

Setup for External Leveling Measurement

 

In Case of Difficulty

If this performance test fails, perform the following steps in order:

  1. Check the equipment setup (see above). If the setup is incorrect, make the necessary corrections and rerun the Performance Test.

  2. If this test fails with the equipment set up properly, 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.
