The software should allow you to easily count the number of pulses or transitions between specified points.

Finally found it... See the section on "Using Measurements (persistent)" at support.saleae.com/user-guide/using-logic/measurements-timing-markers-and-bookmarks

I've owned my Saleae Logic Analyzer for just one day, and I've been trying to figure out how to get it to count the falling edges for a stepper motor control I'm analyzing. It's very important that if I send it 50,000 steps, I get 50,000 falling edges, not 50,001 or 49,999... it must be precise and the numbers are large.. too large to count manually... and I can't count by time because there are accelerations and deceleration involved. I just wanted to add to this idea to let the developers know there is a real NEED for a quick and easy way to count pulses or edges in a specified sample

I storngly appreciate this idea. Maybe in addition or instead of the timing marker pair

It would also be nice to know things like longest/shortest, positive/negative pulse.
Lets say I want to know how long is the longest interrupt in my system.

Duty cycle would also be a very nice feature.
Lets say I want to know the percentage of sleep time my system gets.

Because 「EZ Gear」 does not support windows7, I feel there customers want.
I and our company want to use all means to monitor the CPU output of the motor control.

Followed idea: count of bytes (or analyzer primitives) between time points. Useful for real data rate analyzing.
