    Keysight Technologies N9010A EXA Signal Analyzer Functional Tests Functional Tests Functional tests are tests of various instrument parameters that give a high degree of confidence that the analyzer is operating correctly. They are recommended as a check of analyzer operation for incoming inspection or after a repair.

  • Page 8: Functional Test Versus Performance Verification

    Functional Tests Functional Test Versus Performance Verification Functional Test Versus Performance Verification Functional tests use a minimum set of test equipment to check a much smaller range of parameters (and a limited number of data points for each parameter) than do performance verification tests. Functional tests use limits that are wider than the published specifications;...
