BASIC OPERATION 
In its basic mode, Zeroscope 1U displays the waveforms for both CH 1 and CH 2, and gives you
control over the display height of these two waveforms plus their displayed periodicity.
1. Connect CV or audio signals to either or both the CH 1 and CH 2 inputs.
Both inputs are DC coupled and accept signals between -10V and +10V . Either can serve as a
trigger source, configured to detect either the rising or falling edge of the waveform (as
described later in the Trigger Source discussion). All inputs are normalled to the jacks below .
2. Press the encoder to cycle through the three three basic display options.
Specifically, each press cycles between:
● CH 1 Display Value (volts/division)
● CH 2 Display Value (volts/division)
● T (Time) Display Value (seconds/division,
both channels)
3. Turn the encoder to change the option’s value.
Specifically:
● CH 1 : With this option displayed, turning the
encoder sets CH 1’s gain (height of
displayed signal) between 0.5 volts/division
and 10.0 volts/division.
● CH 2 : With this option displayed, turning the
encoder sets CH 2’s gain (height of
displayed signal) between 0.5 volts/division
and 10.0 volts/division. CH 2’s gain level is
completely independent from CH 1’s.
● T : With this option displayed, turning the encoder sets the waveform’s time base
between 10 s/div and 10 µs/div with seventeen incremental values between these two
extremes.
NOTE : At a setting of 10 µs/div, only CH 1 is displayed. Also, because the Zeroscope
employs a simple anti-aliasing filter, an input signal running at a frequency higher than
the timebase may produce a misleading waveform.
