Stray pulse measuremnt with 7852R

[ken_m]

Hi,

I am working on a test station that contains a PXI 1056 chasis and a PXI- 7852R FPGA. I need to detect stray pulses that are about 100mV and about 750uSec. I can detect the amplitude just fine but I am having trouble measuring the pulse width. Also, once I detect a stray pulse I need to latch the detection indicator. The software I need to modify has a host VI that communicates with the FPGA via the FIFO.

Any suggestions on measuring the pulse wodth would be greatly appreciated.

Thanks

Hi Ken

Below are some examples that you could try.  They were designed for hardware other than what you have, but it should give you an idea of how to proceed.
