I find the possibility to use a low cost USB sound card with WaveForms for some simple student experiments at home, during this pandemic, very engaging for the students. Unfortunately those sound cards have only one input channel and cannot display time delays or phase shifts. I was thinking if there is a possibility to add cross-triggering between the generator (sound card output) and the oscilloscope (sound card input), it would provide them additional insight into circuit behaviour.

Hallo Atilla,
I find the possibility to use a low cost USB sound card with WaveForms for some simple student experiments at home, during this pandemic, very engaging for the students. Unfortunately those sound cards have only one input channel and cannot display time delays or phase shifts. I was thinking if there is a possibility to add cross-triggering between the generator (sound card output) and the oscilloscope (sound card input), it would provide them additional insight into circuit behaviour.
Thank you,
