wrong examples in two signal edge separation folder

[magyar]

In the "Two signal edge-separation" folder the examples are not two signal examples.

They are two edge separation measurements done on one signal.

I am in the need of measuring separation ofrising edges between two encoder signals on 1024 consecutive pulse pairs. I could not find an example for that.

Is there something out there that I could try?

It sounds like you want something like this (Image taken from the M Series User Manual😞

If you want to measure a finite number of pulses, you should use the "Meas Two Edge Separation--Buffered Finite.vi" which is shown in the screenshot in your example finder.  You will have to connect your two signals to the "AUX" and "GATE" inputs of your counter.  On many boards (e.g. plug-in M Series), the default lines used are:

ctr 0:

   AUX:  PFI 10 (pin 45)

   GATE:  PFI 9 (pin 3)

ctr 1:

    AUX:  PFI 11 (pin 46)

    GATE:  PFI 4 (pin 41)

If you don't want to use the defaults, you can modify the PFI lines used with a DAQmx Channel Property Node:

The examples you linked do perform edge separation measurements on two different signals in the manner shown in the above diagram.

This is exactly what I need and it works really well!

Thank you!
