I am looking at an interference pattern signal using a Tektronix DPO 5204B oscilloscope which has windows 7 and TekScope software. This interference pattern grows and shrinks with time (approximately 10-20 seconds for the full cycle). It is my intention to measure the maximum pk-pk voltage and the minimum pk-pk voltage of this cycle without using cursors. The goal is automation of the data acquisition process so that I could perhaps press the SINGLE button and collect data over a small timeframe that contains this interference variation cycle.
Does anybody know a good method(s) to obtain a measurement like this using a similar oscilloscope?
