DAQ board for ADXL202AE accelerometer

[Gino]

I am tring to find a good DAQ board that will be connected to ADXL202AE (Analog Device). It's first time to use this accelerometer. The PDF file is attached. X out and Y out will be used. I also would like to know where X out and Y out can be connected in any DAQ board.

From the manual, it looks like this accerlerometer returns it's values in terms of duty cycle. The manual says you can either use a counter or if you low-pass filter the output, you could use an A/D converter.

So I guess given those two options you could either use one of the counter/timer boards (NI 6601/6602). Or you could use an which could support the analog method. (Actually, the E Series boards have two counters on them so you could use the counter method there too.)

Their user manuals will discuss connections:
6601/6602 User Manual
PCI E Series User Manual

Also, be sure to look through the code library for sample programs. For the counter method, you'll want to look for "buffered semi-period" measurement. That would even be a shipping example if you have LabVIEW.

I hope this helps!
