So you are trying to see the whole transient within a single vertical division? Maybe that's the problem. Set the volts per division to 1V/div, use single shot mode, set trigger vertically to slightly below peak expected voltage, do not set trigger all the way to the left yet. Let's get the peak captured, then we can change some settings to get a display similar to the Spice readout. Just use the normal edge trigger with default holdoff for now. Single shot, rising edge trigger, 1v/div vertically, 500 us horizontally. --- End quote --- Oh jeezbus, I just realized that. I was still thinking in terms of the gate driver for the circuit thats outputting 15v pwm. |O |

Well, did you get a decent capture yet? I'd like to know if my suggested settings or similar actually worked for you. |

Thank you for the replies so far. |

OP, set time base ~ 1ms per division, set vertical to ~ 1V div, set channel to AC coupling, adjust trace to lower position on scope vert divisions and set trigger to lets say ~3~4V. My guess is you have a DC component that is pushing the waveform off the screen. |

Have you tried Auto? It will usually get <something> on the screen and, if your signal actually starts at 0V, you trigger level can be quite low. Just move the trigger point down. I'm assuming a signal that repeats at some reasonable rate. Otherwise, use Single Shot. |
