You will need a digital voltmeter to check power supply voltages, as described on
page 4- -86.
Testing might also be required to correct some faults. Under those circumstances,
you will need the test equipment listed in the Performance Verification and
Adjustment Procedures in this manual.
To determine if the sampling module has failed or the mainframe failed, perform
the following:
1. Perform the module compensation.
2. Perform the measurement procedures you require to make your test.
3. If the the measurement fails, Remove the sampling module and install it into
another slot.
4. Perform steps 1 and 2, then take the following action:
If the measurement successfully functions, there is a good chance the
mainframe channel has failed. Perform other mainframe diagnostics in
this section.
If the measurement fails, there is a good chance the sampling module has
failed. Return to Tektronix, Inc. for repair.
