I've got a 4227 that I've been pulling waveforms off of in Block mode. I would like to run the scope in like a single mode type triggering (my source is activated slightly before I start pulling waveforms) so I get the initial bits of data. Ideally, I'd like to set the scope in single mode, pull my waveforms, and then re-arm the scope again (i.e. reset to single mode).
I've been running my scripts through matlab via MEX files, so the whole procedure would happen in a serial fashion. Currently I'm using ps4000SetSimpleTrigger, and am sure to set a very hold autoTrigger (~10min). However, I would like to move to a Single trigger type mode to ensure that the scope is storing (and pulling) exactly one waveform at a time, and that I'm not pulling something old out of the buffer (and, in Single mode, being able to pull the very first waveforms).
