Spectrum Analyzer Mode Functions
activates the resolution bandwidth function and accesses the softkeys that control the bandwidth functions: BES BW AUTO MAN , VID BW AUTO MAN ,
VBW/BBW RATIO , VID AVC ON OFF , and the
EM1 BW Menu (Also see the HES BW AUTO MAN softkey description.)
(CAL)
accesses the softkey menus used for the self-calibration, service-diagnostics, and service-calibration functions. For more information about self-calibrating the analyzer, see L( lmproving Accuracy with Self-Calibration Routines’ in Chapter 2.
initiates an amplitude self-calibration routine. Connect CAL OUT to the analyzer input before pressing CAL AMPTD Remove the cable from the rear panel GATE INPUT before starting the self-calibration routine.
II N O T E
If the frequency calibration and amplitude calibration self-calibration routines are both used, the CAL FRED softkey function should always be initiated before the CAL AMPTD softkey
I function.
