Frequency response mesurement of an analog filter using only NI 6251 card

[Oichi]

I want to measure and plot frequency response of an analog filter within a frequency range of 0.05-1000Hz, using only one NI PCI-6251 card, LabView 8.0 on a PC windows XP. A hardware function generator may be available, if necessary.

Can anyone help with the program?

Hey Oichi,

After you have acquired your waveform with your PCI-6251 you can perform many different analysis functions on the waveform. On your block diagram goto Programming » Waveform » Analog Waveform » Measurements and you will see the Frequency Response VI's. You can wire your waveform into one of these VI's to perform the measurement. You can also check out the example below.
