make frequency response analyser using frequency generator and counter

[gireesh]

Hello

Can we make a frequency response analyser using a Frequency generator and frequency counter?

How to add modulation with it? Modulation frequency is to be varied as per the input to given to the carrier!

The outputs are Frequency, magnitude, and the phase as like solartron FRA.

somebody have an Idea for this

awaiting for the solution 

thank you

Hello Gireesh,

You can use a function generator to generate frequencies and use the modulation tollkit and other tools availabe with LabVIEW to do the modulation part . Or you can use the analog output ports on the daq card to generate different frequency signals for the same purpose .This should pretty much serve your purpose.
