Hi Joel, 

There's going to be a lot of "if"s in this next text... 

If your service monitor will generate an RF Signal and 
allow an external modulation or sweep input (control). 

A lot of this depends on the range of external control available 
on your service monitor.  

You might be able to set up an external input source and 
sweep a service monitor generated signal. Just as a giggle test 
you might set up an external 10Hz audio input signal (like 
you're trying to input an external CTCSS Tone) and see how far 
and wide the service monitor will allow the external input to 
control the deviation. 

If the monitor sweeps enough with external control, you could 
possibly then connect the same external sweep signal to an external 
sweep or trigger input on your spec analyzer to sync the signals. 
It's not going to be a lot of sweep but it will be some x-value 
amount that you might deem usable or not. 

Wha'la... "a poor mans tracking generator".  I did the above 
trick many years ago to sweep some receiver circuits but that 
was 1984 and now I don't claim to be that old anymore. Plus I 
don't remember the specific details. Since then I've switched to 
Red Wine and all is much betta'

cheers,
