Pulse width measurement with 1 cycle or 1 tone wave ?

[whitewiz]

If we need to measure rise/fall or pulse width of device, we need to apply square or pulse wave from function generator.

Can I use 1 cycle square or pulse wave instead of continuous(CW) 1 tone wave from function generator ?

I want to get the pulse width(50%) of the diode limiting devices.

To apply single pulses you can touch a wire against a battery, etc. I believe this will give the quickest change of state possible.

At first I was going to suggest a one-shot. However this means using devices that take time to switch state. So that doesn't necessarily provide a square waveform.

Likewise with a waveform generator set to 1 Hz. Not ideal.

That means one shot is more desirable than continuous wave form to measure pulse width or fall/rise time.

For a clean one shot you can use a resistor with capacitor connect to either switch relay etc depending the source of the pulse if you have more detail on what you need please do so. Thanks!

I don't know what "the pulse width of the diode limiting devices" means, I guess, also none of the other contributors does. So I don't think, that the answers will help much for your question.

The only way I know of measuring rise and fall times is with an osilloscope.
With a single pulse you will find that very difficult indeed (unless you have a fancy digital one). If your instrument is an analogue one, the pulse needs to be repetetive.
