Spectrum Analysis of Radio Frequency Carriers modulated with video, can be made more comprehensive when the time of observation is assisted by a Video Waveform Monitor's timing circuits.
Anyone who has used a spectrum analyzer to observe a television modulated carrier, knows the difficulty in seeing through all the video signals clutter when looking for spurious signals. Spurious signals, V.I.T.S. and other video RF responses can be observed and recorded easily without interference from other ambiguous video signals.
The technique described in this paper will extend the utility of the Spectrum Analyzer and help provide information that was difficult or impossible to record using the previous techniques.
This paper will assume that you have a working knowledge of the Spectrum Analyzer and the Video Waveform Monitor.
