sample mode average peak detect。。。 for NI scope 5112（eg）

[workstone]

 how can I use the NI scope to acquire wave  as Normal oscilloscope  in  the average (or Peak detect  etc ) sample mode ?

Hi,

For capturing the waveform, I would like to suggest you install the NI SCOPE 18.1 version. It has the function for capturing waveform (just like screenshot) with a clicking of your mouse at the SAME ICON as you are clicking above.

For the compatibility, you can refer to:

  not just only use the front panel VI(exe),  but how can I write or use the sub vi  programing, and algorithm

First, please review the example found here:

<LabVIEW>\examples\instr\niScope\niScope EX Windowing.vi

which shows how you can use the capabilities of the hardware and drivers to calculate averaged spectra. Refer to the documentation to review the default averaging mode and to see what averaging parameters may be set for your hardware.

If you are trying to implement spectrum averaging for post-processing FFT spectra, evaluate the averaging implementation in FFT Spectrum (Mag-Phase) for 1 Chan.vi

Dig into subVIs to find implementation of peak hold, rms averaging, and vector averaging.
