Hi. I'm looking for building vibration equipment. I will measure vibration in the range 0 - 100 Hz.
I need one triaxial accelerometer: PCB 356B18, NI Part Number 784815-01. Is this a difference between measure with PXI or CompactDAQ?
Is this enough to use Chassis cDAQ-9171 with module NI-9230 with triaxial accelerometer PCB 356B18 (784815-01) to get frequency-domain anlysis on my computer? Do I need something else? What will be the difference between NI-9230 and NI-9234. How important is analog input voltage range and what it's impact for accurancy of measurement? What will be the difference if I use PXIe-1071 chassis with module PXIe-4463? Will the measure be better with PXI? Or maybe enough will be USB-4431?
