Qspice Oscilloscope?

QSPICE
1

I updated Qspice today and noticed this update from yesterday:

12/12/2024 Added a sound card-based oscilloscope, spectrum analyzer, and tone generator.

Any chance there is some corresponding documentation about this?

Run one of these, and there is help available within this subprogram.

I see, nice tool. When I saw this my mind jumped straight to hardware in the loop simulation/analysis … maybe in a few more updates : )

In today update, Mike added the feature to allow playback of waveform data.

12/13/2024 Implemented the ability to send a time domain data trace to the sound card if it is longer than 1ms.

Well that was fast :slight_smile:

I initially expected oscilloscope-style controls too, but once I got used to the waveform viewer it covered most of what I needed for quick checks. For frequency-domain debugging, I sometimes compare the results with a simple spectrum analyzer tool like Sound Spectrum Analyzer Online just to sanity-check what I’m seeing. It’s not a replacement for QSPICE, but it can be useful for quick verification.
