exchanges trace A and trace B
puts the difference between trace A end trace B into trace A
puts the difference between trace B and the display line in trace B initially erases trace B end then displays it continuously
initially erases trace C and then displays it continuously turns AM or FM demodulation on and off
changes zero span data to the frequency domain using en FFI turns the marker counter on end off
stops the analyzer sweep at the marker for the defined of the dwell time updates trace A with the maximum level et each point, each sweep updates trace B with the maximum level et each point, each sweep updates trace C with the minimum level at each point, each sweep
the difference between A end B is added tothe display line end put into trace A moves the signal closest to the marker to center screen and keeps it centered finds the highest signal peak, turns on marker track, and activates span
sets a lower boundary to the active trace
starts a routine which adjusts tracking to peak the tracking generator signal starts a routine which digitally averages display signals and noise
holds end displays the trace A data when used after blanking trace A holds end displays the trace B data
holds and displays the trace C data
