I currently have a PCI-7354 Motion card along with a MID-7604 and was interested in using this hardware to acquire vibrational data from a microscope (low g's, resonance in the 250hz to 1.25khz range). I know it's not the correct hardware but i'm hoping to get something up and running quickly. At the end of the day, we'd like to run a FFT on the sampled data and determine the resonant frequency of the microscope stage. I've never really dealt with accelerometers but was thinking i could use the hardware to get a signal into the PC. Just FYI, the Analog input signal inot the MID-7604 is just a pass through and the PCI-7354 has 4 Analog input channels, 16-bit resolution, and ± 10 V range @ 25 μs scan rate (40khz sampling rate?) The specs seem to me to be adequate for acquiring the data, right?
The next question would be if anyone might have a suggestion for an accelerometer (envisioning a small, 50gram puck probe with free leads) for this application?
Thanks!
