How to test trailing and rising edges?

[Schlomer]

Hello there,

I want to test trailing and rising edges. Does anyone has a hint for me how
to resolve this problem?

Thankful for any help.

You can use "Derivative x(t)" VI. Obtain on derivative values that more than some treshold - here founds edge.

Hi,

1. If you want to find out if the edge is trailing or rising then you need to calculate the derivative of your signal and look at its sign.

2. If you want to determine some parameters of edges such as risetime, falltime, slewrate etc. then you have to use
"Functions -> Analyze -> Signal Processing -> TimeDomain -> Pulse parameters.vi"

Good luck.

What exactly do you want to test about them? Rise/fall time, time period
between them, overshoot? What do you have to test them (or how much money
do you want to spend on test equipment)? An expensive scope can tell you
everything you want to know, and then some. A cheap counter can tell you
a little bit. A digitizer and a little math can get you somewhere in
between.

If you provide a few more details we can be more specific in the answer.
