About  QUADSCOPE 

Yezzmod Audio have introduced QUADSCOPE, an oscilloscope, tuner and spectrum analyzer for Eurorack modular synthesizers. QUADSCOPE features dual timebases, four input channels and four buffered outputs, all packed into 10HP.

Four Channels

QUADSCOPE boasts 4 separate input channels with complementary buffered outputs that are accurate representations of the input signals (guaranteed to be with 4mV at DC).

QUADSCOPE has been deliberately over-engineered! The frequency range of each oscilloscope channel goes from milliHz levels up to 25kHz. The oscilloscope input channels and buffered outputs can easily cope with signals that swing well above 11V and below -11V - and QUADSCOPE can also display voltages down to tens of millivolts.

Split Screen Mode

The split screen mode allows different combinations of oscilloscope, spectrum analyzer and tuner to be displayed at once. For example you can display tuners for one or two channels in the top half of the screen while one or two oscilloscope channels (or spectrum analyzers) are displayed in the bottom half.

Dual Timebase

The dual timebase feature makes QUADSCOPE unique when it comes to Eurorack oscilloscopes and we think it’s a game changer. It’s like having two oscilloscopes in the one module (actually, it IS two oscilloscopes in the one module) and allows you to view low frequency and audio frequency signals simultaneously. To do this without dual timebases would require two separate oscilloscope modules - requiring twice the HP, twice the power consumption and twice the price!

Spectrum Analyzer

The frequency components of signals can be viewed with the spectrum analyzer. This is great for visualizing the harmonic content of your modules. The spectrum analyzer supports logarithmic and linear scales and various FFT windowing modes. As with the other QUADSCOPE functions, between one and four spectrum analyzer channels can be displayed simultaneously.

Tuner

The QUADSCOPE can display up to four tuners at once, each with a range of A0 to A7. The reference frequency can be set from 390Hz to 490Hz in 1 Hz increments.

Screen

QUADSCOPE sports a gorgeous, 1.8” high-contrast, color TFT LCD screen.
