Hi Greg, Thanks for the tip. I will give it a try in the nex a few days.

Greg, Do you mean that we can FFT the tacho time signal? It seems a bit odd to me. Tacho signal will be a series of pulses. The shape of pulses can vary a lot.
Steve, I am trying to measure the phase of an analog channel in reference to the tacho input. It is used for rotor balancing...
Hi there,
Can somebody provide a guidance on how to calculate the phase between a vibration measurement channel and the tacho?
I guess people won't use any time domain calculation method to do such calculation. Time domain signals may have noise, and we want to calculate the phase not only...
I think the answer is not that straight-forward. For a half sine acceleration shock, the control system will actually apply the pre- and post- compensation to the main pulse. How the velocity and displacement behave will largely depend on how the compensations are applied. In fact, different...
