LabVIEW Waveform Graph

[abhishekti]

Hello all,

I am working on LabVIEW with real time DSP Processor(SRMK3 board from SoftdB).I have used Waveform Graph to observe my output data.

My output data ranges in between -2.36 V to 3.0 V as I observed in DSO and CRO. But when I used  to check the output data in LabVIEW,it varies in between -5.2e+6(5200000) to +7.2e+6(7200000).

I changed the property of the Y axis(i.e. amplitude) graph from autoscale to user defined  and made the changes from -2.36 V to 3.0 V .After I made this changes also the peak went way ahead of -2.36 V and 3.0 V in negative and positive sides respectively.

I want to get my output in between -2.36 V to 3.0 V in LabVIEW too.

Can anyone tell me where I am getting wrong or what should I use to get the output in range between -2.36 V to 3.0 V .

I have attached the VI and also the DSO Output.

Note:Please check  channel B of DSO.(i.e. Vmax and Vmin of channel B)

Hi abhishekti,

you probably need to scale the integer values you receive from your scope to some meaningful float values.

The needed kind of scaling surely is explained in the manual of your scope and in some example VIs coming with that device driver for the scope. Keep in mind: most people will NOT have that device driver installed…
