Oscilloscope - maximum time window that can be collected?

Hi folks, 

we've just bought 2 of these for work and I am trying to work out what the maximum time window that I can run the oscilloscope to please? From the button I can set it to 5S but if I pinch and zoom I can get to 10S, it then goes to 20S but never seems to hold. 

Thanks

  Hi Nathan,

  Thanks for the question. The maximum time window that you can currently select is 5 seconds, but with the new version of the Pokit App we will be extending this to 10 seconds. You're correct in that when you pinch and zoom you can get it to 10s, but beyond that it will not hold.

  Thanks Lachlan M, 

  What is it that is limiting to 10s? Is it the device or the app? Is there any plans to extend that? Will the PokitPro increase this?

  Am I right in thinking we can't get a live feed from the oscilloscope in 'real time' (well as close as possible). 

  We're trialling these in our business at the moment (marine) with a view to whether we roll out to further staff. The PokitPro is probably more useful to us long term (and I have personally ordered one - just waiting for the day you say they've been dispatched!).

  thanks

  Hi Nathan Quick,

  It is the Pokit App that is limiting it to 10s. This will be the maximum time window that you will be able to select for both Pokit Meter and Pokit Pro.

  You are correct in that that Pokit Meter isn't a typical 'real time' oscilloscope, as it takes a capture then displays it. It is close to real-time, but not an instantaneous reading.

  I would add that given the sampling rate, if you have a high frequency signal, you will lose a lot of information in a 10s time frame
