Is there a way to read the amplitude in addition to the frequency from the MSO using ANSI C?

I am able to get the frequency from the VirtualBench however I have no idea how to get the amplitude of the clock wave.

Hello,

Can you provide more information on what you mean by clock wave? Is it a signal that you're generating? Is it a signal that you're reading in?

Here're some links that might be helpful:

Hi Misbah,

I am using the Mixed Signal Oscilloscope to read a clock signal from a motherboard. There is a computer connected to the VirtualBench that uses a ANSI C program to read information about the signal from the VirtualBench. I looked at the pdf you send me and on pg4 under Waveform Measurement / Oscilloscope Voltage, I'm trying to get the value of the amplitude. Is there a way to do that using ANSI C?

Thanks

Hi Quintin,

Thanks for the clarification.

Are you trying to see the amplitude in VirtualBench or are you trying to use it in your code? 

Also, I found this in another forum post:

If you install ANSI C support during the NI-VirtualBench driver install, after the install completes you should find a VirtualBench C Reference Help.chm at C:\Users\Public\Documents\National Instruments\VirtualBench Documentation as well as example programs at C:\Users\Public\Documents\National Instruments\VirtualBench ANSI C Examples.

If you don't see these files currently, you can go to Control Panel >> Programs and Features >> National Instruments Software, find the VirtualBench ADE Support, and do a modify install.

I'd look into these examples to see if there is one that works with amplitude.

Best,

Misbah
