USB Autoscope Lite – Operation Manual
1. Purpose
The USB Autoscope Lite is used for troubleshooting of various electronic vehicle systems, such
as ignition and timing system. The USB Autoscope Lite is also very useful for engine
mechanical diagnostics. The device is universal in nature and not tied to any particular vehicle
system or brand.
The device works in conjunction with the USB Oscilloscope program and connects to any
USB .0 1 Mbit/s (Full-SPEED) port of a Windows laptop or PC. The Windows version
should be XP SP or higher.
2. Technical characteristics of the USB Autoscope Lite
2.1 General
PC interface type – USB .0 1 Mbit/s (Full-SPEED)
Device supply source – from USB
Current consumption from USB – no more than 1 0 mA
Device provides uninterrupted (frameless) data transfer of digitized data to the laptop or PC
The stream of digitized data is stored directly on the hard disk of the laptop or PC in real time

2.4 Parameters of the USB port's galvanic isolation
USB Autoscope Lite has galvanic isolation of the USB port
(device inputs ground <> PC ground)
Galvanic isolation resistance – not less than 10 GΩ
Galvanic isolation capacitance – not more than 70 pF
Galvanic isolation test voltage – 1 kV for 1 minute
The value of the maximum voltage sensitivity depends on the sampling frequency.

1…4 Connections for analog inputs 1…4. Input voltage range ± 15 V.
5…6 Connections for analog inputs 5…6. Input voltage range ± 150 V.
7USB status indicator.
2.6 Back panel elements
Back panel of the USB Autoscope Lite.
1, 3 Connections "In+" and "In–" are used for connection of high voltage probes.
The signals from the high voltage probes are inversely summed and go to the analog
input 8.
2Connection "In Synchro" is used for the synchronization (trigger) transducer that is used
to detect ignition spark. The signal from the transducer goes to the analog
input 7 through a peak detector.
4Device ground connection. Used to connect device ground to vehicle ground on the
diagnosed vehicle.
5, 6 Pulse polarity indicator from synchronization transducer.
7USB connection. Used for connection of the USB Autoscope Lite
to USB .0 1 Mbit/s (Full-SPEED) port of a laptop or PC. The connection uses a
USB .0 type A-B cable.

2.7 Ground cord
Signal measurements on the analog inputs of the USB Autoscope Lite are recommended to
perform relatively to the black alligator clip of the ground cord. Therefore, before starting the
measurement, the cable must be connected to the back of the device connector (ground) and the
black alligator clip must be connected to vehicle ground on the diagnosed vehicle. When
working with high-voltage probes, this connection is necessary.
In case of breakage of the cable, it can be repaired or manufactured according to the
diagram below.

3.2 Installation of the USB Oscilloscope program and utilities
Insert the installation CD disc in the optical disk drive of the computer.
If the notification "Tap to choose what happens with this disk" appears, left-click
the message screen.
Choose the option "Run setup.exe".
If after inserting installation CD in the optical disk drive of computer nothing happens,
browse through the disc and open the program setup file, called "Setup.exe". The drive letter
your computer uses for the optical drive, often D:\Setup.exe or E:\Setup.exe

USB Autoscope Lite – Operation Manual
If a pop up about unknown publisher of "setup.exe" appears, click "Yes".
You may have to wait while the installer verifies.
In the window "Installer Language", change the installation language if desired.
Then, follow the installation instructions, changing parameters only when required.

USB Autoscope Lite – Operation Manual
In window "Windows Security" activate option "Always trust software from…" then
press button "Install".
If the message "Windows can't verify the publisher of this driver software" appears,
choose the option "Install this driver software anyway".
If a message about the need to install "Adobe Reader" or "Adobe Flash Player ActiveX"
software appears, agree and install the suggested program.
Installation of the additional software may take several minutes.
