USB Autoscope Lite
The USB Autoscope is a new generation of automotive diagnostic oscilloscope and engine analyzer. The device is designed for displaying, recording, and analyzing signals from most all vehicle systems such as:
Sensors and actuators;
Ignition systems;
Fuel delivery systems;
Intake and exhaust systems;
Engine mechanicals such as cylinders, valvetrains, and pistons;
Alternators, starters, glow plugs, batteries …
USB Autoscope Lite is a beginner’s version of the device from the series of eight channel analyzer engines.
The kit is focused on diagnostics of ignition systems, and includes high-voltage sensors for checking both the old and new types of ignition systems. In addition, the kit allows you to check most of the signals from car sensors and actuators.
The capabilities of the kit can be expanded, adding necessary sensors, cables, adapters …
Front panel elements
Connections for analog inputs 1…4. Input voltage range ± 15 V |
|
Connections for analog inputs 5…6. Input voltage range ± 150 V |
|
USB status indicator |
Back panel elements
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 |
|
2 |
Connection "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 |
3 |
USB connection. Used for connection of the USB Autoscope IV to USB 2.0 480 Mbit/s (HI- SPEED) port of a laptop or PC. The connection uses a USB 2.0 type A-B cable |
4 |
Device ground connection. Used to connect device ground to vehicle ground on the diagnosed vehicle |
Pulse polarity indicator from synchronization transducer |
|
7 |
USB connection. Used for connection of the USB Autoscope Lite to USB 2.0 12 Mbit/s port of a laptop or PC. The connection uses a USB 2.0 type A-B cable |
