| Triggering scope with foot pedal switch |

I just jury rigged a foot pedal switch to the external trigger input on my scope with a 1k resistor and 5V supply from scope USB. It's super handy. I wanted to hold two nice high speed probes in particular locations with ground springs and needed both hands for that, but I also wanted to trigger the scope. Enter the foot pedal switch. Surely other people have done this before. I'm looking to make a better / more permanent setup. Do other people have advice on nice ways to do that? I was thinking maybe a little box with debounce, selectable 3.3V / 5V out, selectable idle high / idle low, a BNC jack for output, that kind of thing. |

Food for thought: voice assistant triggering single shot trigger over SCPI. |

Excellent idea, I may build one myself. The most important feature IMHO, would be a debounce circuit. |

A smart pedal would be super cool. Something like this might be more complex than necessary but sounds handy: Hold down the pedal to put the scope in auto or normal mode. Release to stop/hold. Tap once to arm single shot mode. If the scope triggers from the signal, another tap re-arms single shot mode. If not, subsequent taps act like force trigger button. |
