3-9HARMONIC TEST: RF OUTPUT SIGNALS FROM 2 TO 20 GHz

The following test can be used to verify that the 682XXB/683XXB meets its harmonic specifications for RF output signals from 2 to

20 GHz (2.2 to 20 GHz for 68XX5B Models). Test record entries are supplied for harmonics up to a frequency limit of 40 GHz. Additional harmonic checks may be made at any frequency of interest up to the RF output frequency limit of the 682XXB/683XXB model being tested. These additional harmonic checks can be accomplished through the use of waveguide mixers to extend the frequency range of the spec- trum analyzer.
