This test verifies that the internal pulse modulator's rise and fall time for the Pulse Sync Output meets specifications.
Pulse modulation rise/fall time is defined as the amount of time it takes the pulse to transition from the 10% pulse level to the 90% pulse level on both the rising and falling edges of the pulse. The Sync Output is a TTL compatible pulse signal which is nominally 50 ns wide during internal and triggered pulse operation.
During the test, the signal generator is placed in an internal pulse modulation mode and the rise and fall time of the pulse is measured with a digitizing oscilloscope. The Sync Output signal is independent of the RF frequency and power, thus the frequency is arbitrarily set and the power is never turned on.

If this performance test fails, perform the following steps in order:
Check the equipment setup (see above). If the setup is incorrect, make the necessary corrections and rerun the Performance Test.
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.
If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
