Spectrum Analyser Programme

[malkoba]

Hi

I want to view the spectrum of a sweep sine signal from 100 to 1000 Hz. I am taking the input signal (from a mic)through an analog input of a M6259 DAQ card. I am using Labview 7.1. The spectrum analyser programme I have made omits some of the signal and I get a sine+square with some jitter. I would be greatfull if some one can some one check this.

Thanks

Mal

Hi Mal,

From the looks of the signal you have there, the card is only acepting a 0-10V signal. If you go into Measurement and Automation Explorer and use the Test panel do you get the same result? Can you check the signal on a scope or something to make sure its correct?
