Hi,
We are Using PXIe 8135 controller and PXIe 1082 chassis. I want a card compatible with this that can acquire data from an encoder.
Our current requirement is to get data from an encoder with 1000 pulses per revolution rotating at a rate of 6000 rpm.
So the card should be able to read 100,000 pulses per second.
We are using this setup for a vibration analysis. To find the phase angle. (We already have a vibration card).
To get the exact phase angle we need to observe the rising edge of each encoder pulse with a minimum time error.
Therefore sampling at the Nyquist sample rate won’t be enough.
If we can go for a higher sampling rate, it will be the ideal scenario.
I’m thinking of purchasing PXI 6608 (Counter timer card for this purpose).
I would appreciate you guys expert opinion on whether this card will be suitable for our application or not?
And can I use a digital I/O card for this purpose instead of a Timer/counter card?
If so, could you please recommend a card for this application.
I look forward to hearing from you guys
