Measurement of Amplitude and Frequency using LabVIEW

Post by karthin800 » Fri Oct 26, 2018 6:11 am

Hi ,
I'm new to Picoscope. I use 3406D model.
I need to use it for measuring frequency and amplitude using LabVIEW. How should I proceed.? Which VI in Picoscope 3000a library will give me that. ?
Please guide me in steps.
Thanks in advance.

Hi,

There are no measurement features in our SDK.
For say peak to peak use-
Use the 'Array Max & Min Function' just subtract min from max value. See-
http://zone.ni.com/reference/en-XX/help ... x_and_min/

If you want do rms value you use the built in functions-
http://zone.ni.com/reference/en-XX/help ... ed_dc_rms/
but requires the Full or Professional version of LabVIEW
Or use our vi in-
PicoScope.llb/rms.vi
https://github.com/picotech/picosdk-ni- ... oScope.llb

You can do frequency measurement but requires the Full or Professional version of LabVIEW. See-
http://www.ni.com/example/30781/en/
You may have to reformat the input of the array for the this function.
