Zeroscope 1U Manual
Installation
This module is designed for use within an
Intellijel-standard 1U row, such as
contained within the Intellijel 4U and 7U
Eurorack cases. Intellijel’s 1U specification
is derived from the Eurorack mechanical
specification set by Doepfer that is
designed to support the use of lipped rails
within industry standard rack heights.
Before Your Start
Intellijel Eurorack modules are designed to be used with a Eurorack-compatible case and power
supply. We recommend you use Intellijel cases and power supplies.
Before installing a new module in your case, you must ensure your power supply has a free
power header and sufficient available capacity to power the module:
● Sum up the specified +12V current draw for all modules, including the new one. Do the
same for the -12 V and +5V current draw. The current draw will be specified in the
manufacturer's technical specifications for each module.
● Compare each of the sums to specifications for your case’s power supply.
● Only proceed with installation if none of the values exceeds the power supply’s
specifications. Otherwise you must remove modules to free up capacity or upgrade your
power supply.
You will also need to ensure your case has enough free space (hp) to fit the new module. To
prevent screws or other debris from falling into the case and shorting any electrical contacts, not
leave gaps between adjacent modules, and cover all unused areas with blank panels. Similarly,
do not use open frames or any other enclosure that exposes the backside of any module or the
power distribution board.

Zeroscope 1U Manual
You can use a tool like ModularGrid to assist in your planning. Failure to adequately power your
modules may result in damage to your modules or power supply. If you are unsure, please
contact us before proceeding.
Installing Your Module
When installing or removing a module from
your case always turn off the power to the
case and disconnect the power cable. Failure
to do so may result in serious injury or
equipment damage.
Ensure the 10-pin connector on the power
cable is connected correctly to the module
before proceeding. The red stripe on the
cable must line up with the -12V pins on the
module’s power connector. The pins are
indicated with the label -12V, a white stripe
next to the connector, the words “red stripe”,
or some combination of those indicators.
Most modules will come with the cable
already connected but it is good to double
check the orientation. Be aware that some modules may have headers that serve other
purposes so ensure the cable is connected to the right one.
The other end of the cable, with a 16-pin
connector, connects to the power bus
board of your Eurorack case. Ensure the
red stripe on the cable lines up with the
-12V pins on the bus board. On Intellijel
power supplies the pins are labelled with
the label “-12V” and a thick white stripe:
If you are using another manufacturer’s
power supply, check their documentation
for instructions.

Zeroscope 1U Manual
Once connected, the cabling between the module and power supply should resemble the
picture below:
Before reconnecting power and
turning on your modular
system, double check that the
ribbon cable is fully seated on
both ends and that all the pins
are correctly aligned. If the pins
are misaligned in any direction
or the ribbon is backwards you
can cause damage to your
module, power supply, or other
modules.
After you have confirmed all the
connections, you can reconnect
the power cable and turn on
your modular system. You should immediately check that all your modules have powered on
and are functioning correctly. If you notice any anomalies, turn your system off right away and
check your cabling again for mistakes.

Inputs & Outputs
1. CH 1 input: The input is DC coupled and accepts signals between -10V and +10V.
2. CH 2 input: This input, like CH1, is DC coupled and accepts signals between -10V and
+10V.
3. CH 1 output: The signal appearing at the CH1 input jack is normalled to the CH1
output jack, so signals pass unimpeded through the Zeroscope1U. This allows you to
monitor signals without needing to re-patch or use signal multipliers.
4. CH2 output: As with CH1, the signal appearing at the CH2 input jack is normalled to
the CH2 output jack, so signals pass unimpeded through the Zeroscope 1U.
Controls
A. Scope: In Scope or X-Y modes, this screen displays both the CH1 and CH2
waveforms, while in Tune mode, it displays their frequency by either Hz or note name.
B. Encoder: This push-function encoder serves multiple functions — controlling the
appearance of the scope, and enabling both the selection of parameters and the editing
of their values.

Zeroscope 1U Manual
Basic Operation
In its basic mode, Zeroscope1U displays the waveforms for
both CH1 and CH2, 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 CH1 and CH2 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:
●CH1 Display Value (volts/division)
●CH2 Display Value (volts/division)
●T (Time) Display Value (seconds/division, both channels)
3. Turn the encoder to change the option’s value.
Specifically:
●CH1: With this option displayed, turning the encoder sets CH1’sgain (height of
displayed signal) between 0.5volts/division and 10.0volts/division.
●CH2: With this option displayed, turning the encoder sets CH2’s gain (height of
displayed signal) between 0.5volts/division and 10.0volts/division. CH2’s gain
level is completely independent from CH1’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 10µs/div, only CH1 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.

Advanced Operation
Zeroscope1U offers several advanced display and triggering options, located within a
Advanced Settings menu.
1. Long-press (>1 sec) the encoder to open the Advanced Settings menu.
A small menu of options appears to the right of the display.
2. Turn the encoder to select and highlight which of six Advanced Settings options
you wish to edit.
There are six options accessible in this menu. These are, from top-to-bottom:
●SCOPE type
●TRIGGER Source
● TRIGGER DETECTION LEVEL
●CH1 offset
●CH2 offset
●GRID display
3. With the desired option highlighted, push-turn the encoder to edit its value.
That is, turn the encoder while it’s fully depressed to change values. The following
sections discuss each advanced operation in detail.

Zeroscope 1U Manual
Scope Type
With this option selected, push-turn the encoder to select what you want displayed on the
Zeroscope. There are three options:
Scope Standard graphical display, with time displayed on the X-axis and voltage
displayed on the Y-axis.
X-Y Alternate graphical display with CH1 driving the X-axis and CH2 driving the
Y-axis.
Tune Alphanumerical tuning display, which you can configure to show either Hz
values or note names (see below).
Using Tune Mode
Tune Mode displays CH1 and CH2 frequency either by number of cycles-per-second
(Hz) or by Note Name. Once in Tune mode, simply press the encoder to toggle between
the two display options.
NOTE: The input signal must be at least 1V in order for the pitch detector to work.
Hz Display
The top line displays the frequency (in Hz)
of the signal appearing at CH1, and the
second line displays the frequency of the
signal appearing at CH2.

Zeroscope 1U Manual
Note Name Display
The top line shows CH1, and the second
line shows CH2.
Zeroscope displays the note name closest
to the incoming pitch, plus a vertical line
indicating how far the pitch is from that
note (from -45 to +45 cents).
A note is sharp if the vertical line is to the
right of the note name. For example, in
this illustration the vertical line is to the right of the note name for CH2, indicating that
CH2 is playing a C3 (“middle C”), but that the note is sharp.
A note is flat if the vertical line is to the left of the note name.
A note is perfectly in tune if a box surrounds the note name. In this illustration, the box
around the note name for CH1 indicates that it’s playing a C1 note, and that it’s perfectly
in tune.
Reference Pitch and Averaging Time
Both the Hz Display and the Note Name Display have two additional options at the
bottom of the scope: ref and avg.
ref This displays the reference pitch used by the tuner (which displays the
number of Hz to which the A above middle-C is tuned). Most devices
default to 440Hz, but other standards are sometimes used.
avg This displays how long the Zeroscope spends averaging out frequency
variations before it recalculates and reports a new note name. There are
three options: slow; norm; and fast. Fast is very sensitive to fluctuations
on input, while slow is not. Norm is in the middle.
A small indicator arrow to the left of the ref or avg parameter indicates which will be
changed by rotating the encoder. To change whether the encoder edits ref or avg, switch
between Hz and Note Name displays. Specifically:
1. After entering Tune mode, wait five seconds for the little Tune mode indicator in
the upper right corner to extinguish.
2. With Hz display active, turn the encoder (without pushing it) to change the avg
setting (slow, normal, fast)
3. Switch to the Note Name display, and turn the encoder (without pushing it) to
change the ref tuning value.

Zeroscope 1U Manual
Trigger Source
With this option selected, push-turn the encoder to select how you want to trigger the
Zeroscope. You have five triggering options:
Trg off The scope is untriggered
Trg 1 The scope triggers on the rising edge of the signal at CH1
Trg 1 The scope triggers on the falling edge of the signal at CH1
Trg 2 The scope triggers on the rising edge of the signal at CH2
Trg 2 The scope triggers on the falling edge of the signal at CH2
Trigger Detection Level
With this option selected, push-turn the encoder to set the level at which trigger detection
occurs. Trigger threshold can be offset ± 10V (-10000µV - +10000µV). At 0V (the default), a
typical bipolar waveform triggers when it crosses the 0-line.
Trigger levels are graphically indicated on the Zeroscope display.
If you set a trigger threshold beyond the voltage limits of the current waveform, you’ll see a
small T? icon appear in the lower left corner of the display, indicating that it failed to detect a
trigger.
CH1 Offset
With this option selected, push-turn the encoder to set a display offset for the CH1 waveform.
Waveforms can be offset ± 10V (-10000µV - +10000µV).
Offsetting waveforms is particularly useful
if you want to display CH1’s waveform
above (or below) CH2’s waveform. For
example, assume CH1 and CH2 are
both typical ± 5V waveforms. If you set
both the CH1 and CH2 Display Values to
5.0 V per division, then each waveform is
½ the entire height of the scope. If you set
the CH1 Offset to +5000 (+5V) and the
CH2 Offset (described below) to -5000
(-5V), then CH1’s waveform is displayed
in the top half of the scope, and CH2’s is
displayed in the bottom half.
