How to measure a pulse about 8us wide?

I suspect that 8us is too narrow for pulsein. If so how could I measure a pulse of this width, please?

You could do it using hardware timers on a fast processor like a Teensy 3.x / 4.x or an ESP32.

I have ordered a teensy 4.0.
I'll see how it goes...

I can not give a general answer. With ESP32 running at 240 MHz for example you can take a digital sample like once per us and analog sample like once per 8 us (with I2S interface). I guess this is the most you can get out of it without using a special HW.
