1. Set the AC power source output equal to the required line voltage
and frequency. The analyzer under test should be operated at 400
Hz and the source analyzer at 50 to 60 Hz.
2. Allow both analyzers to warm up for at least one-half hour with
LINE switch in either STANDBY or ON position.
3. Perform frequency calibration of each analyzer as specified in step
2 of standard instrument procedure.
4. Connect 1ST LO OUTPUT of source analyzer to RF INPUT of
analyzer under TEST and key in settings on source analyzer as
specified in step 12 of standard instrument procedure.
