Operational Checks

Performance
Verification
After selecting the active test set, perform the system calibration procedure
as usual. When you select a different test set, make sure you recall the Cal
Set that applies to that test set.
Since the Cal Set Limited Instrument State does not include the number of
the active test set, a Cal Set which does not apply to the current test set can
be turned on without any HP 8510 caution messages appearing. This will
cause errors in the displayed data because incorrect error coefficients are
applied to the measured data.
To check the operation of a multiple test set configuration, connect a device
with a known response at test set number 2. Press:
1. HP 8510 [ ] {
LOCAL test set
2. Enter the address of test set number 2 (this would be 20)
3. Press [ ]. The test set number 2 measurement should appear.

trace for later comparison. Use {
number 3.
5. Switch back to test set number 2. Observe any difference in the response
between the stored trace and the result after switching back and forth
between the test sets. Any difference in the data believed to be due to
Option 001 IF switch or RF switching, must be investigated.
Standard system performance verification procedures are used to verify the
operation of the Option 001 test set as test set number 1. To verify the
performance of another test set in the chain, select it as the active test set and
proceed as usual with the HP 8510C On-Site Service Manual performance
verification procedures.
