Hello all
I work in a laser laboratory. We use a photodiode to detect our laser pulses and this signal is fed to the oscilloscope's BNC input.
I have a Python program that I have written with the wrapper PicoTech supply. My ADC counts for the laser pulses are below:

I also have a LabView program that is an extension of the one supplied by PicoTech. My ADC counts for the laser pulses in that instance are:

You can see there's a factor of 10 difference between the ADC counts for Python and LabView and I cannot for the life of me find the parameter to change to improve Python's ADC counts. Both programs have the same triggering parameters, pre- and post-trigger samples, timebase and are using block capture,
Any advice anybody can offer?
Many thanks
Jamie
Different ADC counts in LabView and Python?
Re: Different ADC counts in LabView and Python?
Hi Jamie
Are the voltage ranges in both programs being set to the same value?

Hello Neil
Yes, both 5V ranges.
Thanks

Re: Different ADC counts in LabView and Python?
Doh! Just realised that the Pythonic implementation goes through the ADC2mV function... So I'm comparing ADC counts with voltages!
Apologies.
