Signal acquiring

[basanth]

Hi,

       I am using PCI-6221 Ni card to acquire the Signal. I am facing problem with Signal detected from a integrated 

Photodiode (PDI-400 hickl and Becker) I get the spicked signals when I connected to the my ni card and  with port as AI 15

n samples, freq-1000,  samples 1000 as parameters. I have written a labview program which ac quires the Signal through DAQ assistance and output is given to graph plot.

Don't know about anybody else, but I couldn't read this question.  All garbled up and the picture was missing.

Me neither.

Basanth,

You can't insert an image that is located on your harddrive.  No one else but you can see it.  You need to post the image file (prefably .png)  as an attachment to your message.  Once you submit the message, then you go back and edit the message and insert the image (as long as its not too big) based on the link to the image as it resides on the NI forums website.

Please retype your message so that we can see all of it.  It seems to have been cut off.  There is some crazy HTML code type stuff at the end and we don't know what your question is.

Sorry for the inconvenience,

 This is the signal acquired from PCI -6221.Shown in a graph chart of labview program.

I have used AI-15 port to input the signal Sampling rate 1000,frequency is 1000.

I want the signal to see as some numer like eg 2V , 3V in the graph chart how to do it.

OK, that helps a lot.

First suggestion is to try to acquire the data using the test panels in NI Max.  If you can, it's your software.  If you can't, it's your instrumentation setup, wiring, etc.  You might have it set up as RSE when you really want it differential or something...
