PERFORMANCE TESTS
The analyzer's performance tests consist of the 21 tests listed in Table 1-1 . These tests verify
that the analyzer's performance meets the guaranteed specications. See the
Operation
Manual
for the specications.
The analyzer's performance is categorized into two groups; performance in the network
analyzer mode and performance in the spectrum analyzer mode. The third column in Table 1-1
indicates to which group the listed performance test belongs.
All tests can be performed without access to the interior of the instrument. The performance
tests can be used to perform incoming inspection, and to verify that the analyzer meets
performance specications after repair.

The test numbers in Table 1-1 are numbered according to the recommended sequence of
performing tests. When performing more than one performance test, perform them in the
order listed in Table 1-1 . The rst failed test indicates the problem you should troubleshoot
rst.
If the performance tests indicate that the analyzer is not operating within the specied
limits, check the test setup. If the test setup is correct, see the
Adjustments
chapter or the
Troubleshooting
chapter for corrective action.
Note
Allow the analyzer to warm up for at least 30 minutes before you execute any
of the performance tests.
Perform all performance tests in an ambient temperature of 23
6
5
C.
