Aand you forgot to switch the probe to 10X again :palm: Really, make this a habit when you probe digital signals or anything above audio frequencies: Your probe in 1X mode has a bandwidth of maybe 5 MHz, which means you basically get to see the fundamental tone of the square wave and all higher order harmonic will be attenuated a lot. So you see a distorted sine wave at best, but not the true waveform. |

Oh my god! But you pegged me perfectly: I'm an audio enthusiast, and I mainly play with amplifiers etc Give me a moment, I'll redo it... |
| pizzigri:

OK. Is that with or without the GPIB card connected? I'd like to see both. |
| pizzigri:
Without, this one is with. The shape doesn’t change much but amplitude is less |
