Before You Start
Periodic verification of operation
The analyzer requires periodic verification of operation. Under most
conditions of use, you should test the analyzer at least once a year with
the complete set of performance verification tests.
Test equipment you will need
The following tables list the recommended test equipment for the
performance tests. The tables also list recommended equipment for the
analyzer adjustment procedures which are located in the Agilent ESA
Spectrum Analyzers Service Guide. Any equipment that meets the
critical specifications given in the table can be substituted for the
recommended model.
