UNTRANSLATED Four-channel oscilloscope, and much more ========================================
Eyes17 comes with an application whose default User Interface is an enhanced four-channel oscilloscope.
- Link to YouTube videos
- The Oscilloscope program mainly functions as a four channel oscilloscope, with inputs A1, A2, A3 and MIC.
- Adjust the x-axis limit of the graph, using the Timebase Slider, generally to view several cycles of the waveform.
- If the waveform is not stable, select the proper trigger source. If needed adjust the Trigger level.
- The traces can be saved to a file, in text format. It is possible to take the Fourier transform and view the frequency spectrum of the input waveform.
- The oscilloscope program also has control/monitor widgets on the right side panel to access most of the ExpEYES features.
- The inputs A1, A2, A3 and the resistance connected to SEN are measured and displayed every second. But these readings are meaningless when AC inputs are connected.
- For sinusoidal AC inputs, enable the Check-Button in front of the channel widget to view the Peak voltage and frequency.
- The ExpEYES Input/Output terminals are briefly described below.
Output Terminals
- CCS:
Constant Current Source. On/Off using Check-Button
Enable CCS. - PV1: Programmable Voltage,
range. Can be set using the
Slider or Text-Entry widget - PV2: Similar to PV1, but ranges from
to 
- SQ1: Square Wave Generator, swings from
to
.
Frequency can be set from
to
. - SQ2: Same as SQ1, but available as an option of WG.
- OD1: Digital Output, voltage can be set to
or
. - WG: Waveform Generator. Frequency from
to
.
Amplitude can be set to
,
or
.
Can be set to Sine, Triangular or Square.
In Square mode the output is on SQ2, with
to
swing. - -WG: Inverted output of WG
Input Terminals
- IN1: Input for measuring Capacitance. Push-Button provided for measurement.
- IN2: Input for measuring frequency of digital signals, swinging
between
and
to
.
Push-Button provided for measurement. - SEN: Input for measuring resistance. This point is internally
connected to
via a
resistor - A1: Voltage measurement point, functions as voltmeter and
oscilloscope. Maximum Input range
, range is selectable
from pull down menu. AC/DC mode selection by slider switch on the
box. - A2: Same as A1, but no AC coupled mode
- A3: Voltage measurement in
. Small signals can
be amplified by connecting a resistance from Rg to Ground - MIC: Condenser microphone input, output appears as the fourth channel of the oscilloscope
- Rg: Gain resistor for A3.

For example connecting a
resistor gives a gain of
