Frequency response in Labview

Post by Guest » Fri Aug 27, 2004 3:50 am

G'day Folks

I am currently writing some code in Labview 7.0 using an ADC-200 to measure the frequency responses of basic filters using a sineswept input.

I have tried connecting some Labview modules (FRF, CROSS etc) to the output of the but I don't seem to be getting a proper response either with the magnitude or phase.

I can measure the signal and calculate the FFT but the responses are not correct.

I was just wondering if anybody has done something similar or knows of similar code using Labview and the ADC200.

I am sorry to hear that you are experienging problems with Labview and ADC-200, there are very simple examples availalbe sowing how the routins should be used, but may not go far enough on the labview side for you. The example scan be downloaded by following the appropriate button at the bottom of the page.

Perhaps someone else on the forum will be able to assist with the Labview code.

Best regards,

Mark Spencer
