Duty cicle measurement about openhantek6022

@thalst Good proposal!
Please have a look at the latest commit 473221e
Now the top line shows the width of the pulse after trigger and the following pulse as well as the duty cycle: /1.00ms\999µs/ (50%)

You can measure rise / fall time easily with the drafting compass menu on the left.

That's easy, we have e.g. a 2kHz square wave with frequency peaks at 2, 6, 10, ... kHz. The horizontal dock lets you select the frequency base for the display of the spectrum, in our case "Frequencybase 1kHz" (1kHz/div), so a peak at division 2, 6, 10. (The left margin is always 0Hz).

You can set the frequency resolution in the same way as the time per division -> same frequency, but with "Frequencybase 10kHz"

The bottom lines display also the fundamental frequency of the measured traces on the right (2.000 kHz).

Awesome!!! Another question: do you have some material regarding the spectrum measurement and how to interpret it? I'm having a hard time finding the frequency for a given spike in SPx

I dont know how to thank you. It's a great work. I'll be throwing more ideas in a few days if you don't mind.
