PC Measurements

Spectrogram

Spectrogram version 5.0 is a freeware dual channel audio spectrum analyzer for Windows 95/98/NT which can provide either a scrolling time-frequency display or a spectrum analyzer scope display in real time for any sound source connected to your sound card.

BIP Oscilloscope

The BIP Oscilloscope uses the sound card's input to measure signals. This means that the quality of the scope depends on the quality of your sound card.

Zelscope

Zelscope is a Windows software that converts your PC into a dual-trace storage oscilloscope and spectrum analyzer. It uses your computer's sound card as analog-to-digital converter, presenting a real-time waveform or spectrum of the signal - which can be music, speech, or output from an electronic circuit. Zelscope features the interface of a traditional oscilloscope, with conventional gain, offset, timebase, and trigger controls. As a real-time spectrum analyzer, Zelscope can display the amplitude and phase components of the spectrum.
