I work with industrial automation equipment and need to accurately measure the time interval between two separate inputs going high (rising edge). Each of the inputs is 24 VDC and each event lasts anywhere from 1 to 40 milliseconds. We are currently using an expensive Ethernet packet monitoring tool that supports physical inputs with a resolution of 20 nanoseconds. The software that comes with this device can record and plot successive events and compute the average of all the samples. We generally run the test for 1,000 samples.
Is there a way of using Labjack hardware and software (or third party stuff) to do the same thing without this becoming a science project for me? I'm really looking for a lower cost solution that me and others in my group can easily use.
Thanks in advance,
