MDS Audio Oscilloscope / Spectrum Analyser

MDS Audio Oscilloscope / Spectrum Analyser converts your computer into dual channel digital oscilloscope and spectrum analyser.

As digitizer application uses PC's audio card. Many audio cards has fequency response up to 90 kHz and this is more than enough for measurements in the audio spectrum range.

Powerful signal reconstruction enables to visualise signals correctly at frequencies, close to Nyquist frequency.

Channels can run in two modes: like in conventional oscilloscope using same time and amplitude axes for both channels, or independent axes for the each channel !

Triggers for the each channel might be independent as well! You can use this application as two different single channel oscilloscopes.

An automatic Y axis scale adjustment allows to keep waveform fully visible, when it moved close to upper or bottom window edge. It shrinks waveform moving to the edge and expands it moving to the center.
