SINE WAVE FPGA

[Prashant R. Bhangre]

Labview :- 8.2
NI cRIO :- 9004 (CompactRIO Real-Time Controller)
FPGA
NI9221 (8 channel, +-60V,analog input)
 

I am preparing scope to capture sine waves with above mentioned system.

I am giving sine wave input to my 9221 (800 KS/second.). But on scope it is not showing the proper sinewave.

Some sampling problem might be there.

Also i read one post regarding the same problem.It is suggested to change the Calibration Mode in Module Configuration of the analog ouput to Raw.
But i didn't find this option.

Please guide where I can find this option?
 
Please suggest how to resolve this as I am new to Labview.

Hi,

First of all there is no option to set the calibration mode under LabVIEW 8.2. This was first available with 8.5.

You will need to provide a bit more information on the signal you want to acquire (frequency, ..) and what are the results you get?
Did you also try to run one of the examples? Use the LabVIEW Example Finder and go to Modules and Toolkits>compactRIO>Module Specific>9211.

Hi,

           I am a student and doing my academic project on labview. I want to develop Labview program to act as oscilloscope. I have NI cRIO-9221. this from this i can take 8-anlaog inputs. so i want to see these 8 analog inputs results or waveforms in labview fpga program. so this is my task.

please help me.

Thanx in advance..
