Hi everyone, I'm new to the group and fairly new to Pico scopes. The school where I work has a few 3423 automotive kits and I am running version 6.10.11 software. 

I am attempting to capture EVAP monitors in action to teach system operation in class. I can't seem to get enough recording time to catch the entire monitor at a high enough level of detail when zoomed in.

My question is, is there a way to determine, in advance, the maximum recording time for a specific time base and sample rate? Other than set-up the scope and let it run until the buffer is full and calculate total time.

I am currently sampling @300Kbs, 10,000 waveforms, 1 sec/division, which provides me 84 waveforms or 14 minutes of recording. If I push the time base to 5 seconds/division, then the detail in the waveform is insufficient for our purposes when zoomed in.

Thanks in advance for your help,

What school would that be?  We have support colleges all over the continent.

Yes, we have charts for that available to our Picogroup members.  PicoScope assistance is provided in the Picogroup members only areas, but I can give you a couple of pointers.

If you are referring to your requested number of samples, then turn that up to the max.  With a 3423, you should just leave that there all the time.  If you want a seamless recording, choose a time base for the time desired so that you have it all on one screen. 

For example, a 1000 second capture time (over 16.6 minutes @ 100s/div) will render a sample interval of 477 microseconds or about 2kHz using a 3423.

Might be time to think about upgrading those with us.  Then you would have access to the Picogroup resources.
