I am using NI sound and vibration suite first time, I am trying to build a project to monitor and record generator and turbine vibrations, I use cDAQ and cards to get signals from Bently Rack BN 3500. I want to monitor and aquire the vibration amplitude, unit speed, monitor and analyis spectrum, 1X amplitude, 2X, etc, phase angle, do the polar and bode plots, I attach a project i built, but it look to me not good, can anyone show me an example or guide me through the project i built?
I tried to run the project, there was a erorr "tachometer pulse not detect", the vibraiton signal scale is 200mV/mil, when I want to put scale, do I use Add step-->scaling or something else?
Thank you very much for your help.

Yutao,
My first instinct on receiving that error is to make sure that my tachometer is reading data. Try to acquire data from your tachometer in MAX and then with an example project in the assistant. The error basically says that the program never received data so lets make sure it is receiving data.
