CP2100A current probe measuring frequency
chrisb741:
I have wired everything up again
Same circuit with same resistors. The load is 1A CC from a SDL1020X instead of the LED strip
The ORANGE current probe is attached between the MCU and the resistors
The PURPLE Diff Probe DP1007 is attached across 100R
The pulse is On for 1us Off for 1us
Noy:
Beside the other answers.
Micsig CP2100A/B are nearly the same HW. As far as i know there wera / are a few probes which have matching specs even if they are labeled A/B.
I think there was although a hacking thread abaout these probes.

It would be interesting to see a picture of your real setup.
I should still have IRF540N, I might rebuild the setup, but with a generator.
Kanbus:
Semi unrelated question.
Won't you get unexpected results by using an electronic load? While your mosfet is off, the e-load circuitry will switch hard on to try and maintain the 1A. Then you'll have a dead short while you turn on your mosfet and until the e-load's regulation catches up again.
