Re: Tektronix 492BP Spectrum Analyser Repair: Only fundamental 0-1.8GHz band works

The PEAK John was talking about is a knob that allows you to
tune the center frequency of the YIG Tuned Filter to peak at
the frequency of the YIG Tuned Oscillator. In other words, make
the two YIG's track each other more perfectly.

It is simply adjusted for maximum signal amplitude in the swept frequency
range of interest.

The PEAK/AVERAGE knob, if I recall correctly, divides the display
into an upper region, and a lower region. The signals displayed
above the dividing line are using a peak detector, and the signals
displayed below the dividing line are using an averaging detector.

It has nothing to do with what John was suggesting.

Hi John,

Thanks for your help.

Is there a section in the manual that explains what the peak/average knob does? Im not quite sure what I am testing with what you suggested above.

Thanks
