Sound-card oscilloscope

October 27, 2008

My ham and audio-nut Rob tipped me of to a fully featured but free software that turns your PC sound card into an audio-frequency scope. It even does X-Y mode so Bob Pease would approve, if he doesn’t throw the PC off the roof first.

Yes, a sound card can do quite well in audio frequency range, but be careful when you measure external voltage and do not measure voltage greater than 5V without attenuating the signal first. For convenience and safety, you may need to make a test lead or probe with input protection like the one at: www.multi-instrument.com

A sound card provide high-quality playback through computer speakers. A sound card plays voice as well as music files, and can handle various audio file formats including .wav, .mp3 and .cda to name but a few. The typical sound card has an interface available at the back of the computer with various input and output ports.
