It is a truth universally acknowledged, that a
single ham in possession of a good fortune, must be in want of a oscilloscope. At Hamvention, I bought slightly more of an oscilloscope than I needed, a Rigol DS1102E.
After calibrating the probes, I cast around for something to measure. Aha! There lay anÂ Atari Punk Console (previously) ready to show the world what its waveforms look like.
Surprsingly clean output here.
Ahh, the notorious APC “squelch-fart” noise. The poor little speaker hasn’t a chance of reproducing this, so it collapses into spasms.
A noisier high frequency signal from the APC.
The Rigol is pretty easy to use. These images were captured via its USB screen dump feature; no need for an oscilloscope camera here!
