[Premium-Rx] spectrum Analyzer to use as a signal monitor

[w3jn]

I think you misunderstood what I said.   The MAX HOLD feature on analyzers 
such as the Tek 492/494 and HP 85xx series holds the max for all successive 
sweeps until turned off.

WHat I'm saying is that the sweep speeds are slower, and to compensate for 
that, the pixels stay static as the analyzer sweeps, then they of course 
reset when the analyzer starts the next sweep.  THis means "stop animation" 
displays rather than displays that smoothly change in concert with the 
signal's modulation.  No other way they could do it, really, given the 
overhead of digitizing the detector output, putting it into memory, etc. --  
I just find it annoying and prefer analog, fast swept displays.
