I recently purchased the 3206D MSO and have been using it to observe and capture intermittent pulsed waveforms. I have been able to use the alarm feature to save captured waveforms to disk. This works fine when I am physically present at my scope/laptop setup and am there to stop the capture when I have enough recordings. I want to do unmonitored recording of waveforms to disk. The input has an arbitrary number of pulses which trigger recording. But I want to limit the number of captures so that I have only some fixed number of representative ones without the danger of filling up the disk over long periods of time.
How can I do this ? Any help would be appreciated.
