c. Under Select Action, click the Compensate option button.
d. From the top pulldown list, choose All (default selection) to select the
main instrument and all its modules as targets to compensate.
e. Click the Execute button to begin the compensation.
f. Follow the instructions to disconnect inputs and install terminations that
will appear on screen; be sure to follow static precautions (see the user
manual for your sampling module) when following these instructions.
NOTE. Failing to install the 50 Ω terminations on electrical inputs can yield
erroneous compensation failures or results.
2. Verify that the compensation routines pass:
a. The compensation may take several minutes to complete. Verify that
Pass appears as S tatus for the main instrument and for all sampling
modules listed in the Compensation dialog box when compensation
completes.
b. If instead Fail appears as Status, rerun the compensation. If Fail status
continues after rerunning compensation and you have allowed warm up
to occur, the module or main instrument may need service.
c. If you want to save the compensation constants generated by this
compensation, click the Save option button under Select Action. Click
the Execute button to save the compensation.
3. Close the compensation dialog box.
End of Procedure
Perform the Functional Tests
These procedures use the DC CALIBR ATION OUTPUT and the INTERNAL
CLOCK OUTPUT connectors to further verify that the instrument functions
properly. An S MA cable and a 10x attenuator are required to do these test
procedures.
The purpose of these procedures is to confirm that the instrument functions
properly. The equipment required is intentionally kept to a minimum.
