I've been trying to get the block mode example VI to run correctly with a trigger on a 3424 pico scope.
I noticed that when i press run, the graph will trigger even though the instrument that is supposed to trigger the scope isn't running.
I then disconnected the BNC cables from all channels of the scope, ran the vi again, and it would still start taking data with out waiting for the trigger event.
After pressing stop on the labview VI, the graph shows a really large square wave right a the start of the graph. Around 40 V!
I connected the picoscope to a waveform generator to aid in trouble shooting this issue.
I noticed the same issue as before where you can see the huge square wave at the start of the graph and then some data from the function generator.

When i use the picoscope software, i get the following image which is linked below. http://img196.imageshack.us/img196/2181/fromsoftware.png
Hopefully someone has run into this issue before and it's an easy fix.
Thanks for reading my post.
