Operation
After selecting the active test set, perform the system calibration procedure
as usual. When you select a different test set, make sure that 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 8510 caution messages appearing. This will cause
errors in the displayed data because incorrect error coefficients are applied to
the measured data.
It may be convenient to store a hardware state file and an instrument state
file for each combination of test set and cal set. You may also store your
hardware state file on a disk for future use. To change the configuration,
simply recall the appropriate hardware state file, which sets the address of
test set and issues the RF switch command, and then the appropriate
instrument state file which recalls the cal set.
To check operation of a multiple test set configuration:
1. Connect a device with a known response at test set number 1.
2. Press 8510 ,
[LOCAL] {TEST SET]}
3. Enter the address of test set number 1 (this would be 20).
4. Press . The test set number 1 measurement should appear.

for later comparison.
6. Press 8510 ,
[LOCAL] {TEST SET]}
number 2.
7. Switch back to test set number 1.
8. Observe any difference in the response between the stored trace and the
result after switching back and forth between the test sets. Repeat for
each of the test sets. Any difference in the data believed due to the
Option 001 IF switch or RF switching must be investigated. Refer to
Chapter 6, "Test Set Troubleshooting"
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 a test set other than an 8511 in the chain, select it as the
active test set and proceed as usual. Refer to the Agilent 8510 On-Site
Service Manual for the performance verification procedure.
