I understand at least part of this has been discussed elsewhere in the forum but I'm hoping for more specific answers.
I have a 3206D MSO that has 512MS memory and am using PicoScope 220.127.116.119 beta. I am trying to capture as much as possible at a 500ns sample period. I need a trigger channel and a data channel. Both are digital outputs. I also need to use the post-trigger delay. I do not need to record the trigger channel. I am using a single shot trigger.
First there seems to be a limit of 100MS. If only channel A is enabled I can select 5s/div and the samples control to 100MS or greater and get 99,206,347 samples at 504ns/sample. if I select 10s/div the sample interval increases to 1us. Increasing the samples control does not help. I return to 5s/div then enable channel B. My sample depth drops to 50MS. I have 512MS and am only using 2 channels, and the trigger is set to single. Please explain.
I was recording 100MS using the digital channels but also needed to use the post-trigger delay which was greyed-out when using digital. It's also greyed-out now with only analog channels enabled. What am I missing? Should this feature be available with digital channels enabled? I also thought the 100MS limit was a digital issue and I would have increased depth with only 2 analog channels.
