Labview VI design for Digital Oscilloscope for Digilent Discovery 2 FPGA

[Ayesha Zaman]

Good Afternoon

I am trying to design a Digital Oscilloscope for the Digilent Discovery FPGA system using labview.

I have the AD2 and Digilent Waveforms VI installed as the Instrument Driver in Labview. But I need to modulate the Resolution Bandwidth (RBW) for the Oscilloscope design. I find two algorithms being used as FFT and CZT within Waveforms. By passing Waveforms software I will be designing the VI using labview , where I should be able to vary the Resolution Bandwidth for the Digital Oscilloscope . 

Do I need to install any other driver for the design?

I would highly appreciate your feedback please.

Thank you so much.

Hi @Ayesha Zaman

FFT/CZT function is available in WF SDK as C API but you can use similar VIs to process the raw data.
