VFREQ, this selection is active for revision F only. Program frequency must be set
between 360Hz and 800Hz to run the tests.
60Hz, this selection is active for revision F only. Program frequency must be set to 60Hz

the normal setup screen. Selecting the nominal test frequency in the 704 Application screen does
