My use is very simple. I don't have a UHF signal generator, so I use the NTSC video carrier of the modulator as a constant strength test signal. All I have to do is select an output channel on the Agile Modulator and tune my signal level meter or SDR to that frequency. It isn't necessary to modulate the carrier, the video carrier exists without video or audio input.
For VHF, I use a more sophisticated (and expensive) source; I generate an ATSC 1.0 carrier with my Thor Petit Modulator.
