To perform the 8960 Operational Verification tests requires that the 10 MHz成人英语怎么说
timebas be connected together. Connect the 10 MHz Reference Output of the 8960to the 10 MHz Ref In of the ESG E4433B. Connect the 10 MHz Ref Out of the ESG E4433B to the 10 MHz Ref In of the VSA E4406A with BNC cables.
The RF In/Out Connector of the 8960 will be alternately connected to either the RF Out of the ESG E4433B (RX Test) or the RF Input of the VSA E4406A (TX Test) with a low loss Type-N cable.

8960 Operational Verification
Analog Generator Level Accuracy Analog Generator Level Accuracy is a test to insure that the 8960 can t a basic level and then step in 10 dB increments accurately.
The expected limit is:
RF Generator Output Level, RF In/Out (2 sources) - ± 2.0 dB
The current operating firmware in the 8960 does not allow manual operation of
amplitude or frequency using incremental steps for either Signal Generator 1 or 2; a PC with controlling software is required.
