Automotive Signal Generator for simulation of sensor signals

Since its releasing in 2012, the AutoSim sensor simulator has proven itself extremely popular with both technicians and professional diagnosticians thanks to its friendly user interface, attractive and reliable operation.

Eight years on from the release of the original model, we from Ditex present the second generation AutoSim Pro. Distinguished by its completely updated design and significant functional improvements, the AutoSim Pro Automotive Sensor Simulator from Ditex is a very useful tool suitable for both cars and trucks applications in a variety of working situations. This advanced sensor simulator creates an electrically equivalent system to simulate the sensors and actuators found on an actual vehicle.

In general, the AutoSim Pro is a specialized signal generator for testing sensors, including leads and connections when installed. In this way, it is possible to tell whether an ECU, a feed, a plug-in connection or a sensor is defective. This allows efficient fault elimination without replacing parts "on suspicion". One of the special features of this device is its easy and intuitive operation via function keys. The display continuously shows the most important settings such as current waveform, frequency, amplitude, offset, ramp time and pulse width.


Signal generator

Providing the most important signals: sine, square, triangle and ramps, up to 20 kHz make the device the ideal companion for experiments with all type components and sensors as well as for the analysis of electrical wiring circuits. You have complete control over the output signal: peak-to-peak amplitude, frequency, duty-cycle and pulse width. A microcontroller sets the output voltage in the range of 0V to ±12V accordingly to the programmed curves.


PWM generator for the dynamic control of vehicle actuators using pulse width modulation. The PWM generator function was specially designed to control flaps, actuators, valves, injectors and smaller DC motors. Generating variable power PWM signal up to 4 A.

Precise DC voltage source

The AutoSim Pro low-noise, high-resolution DC voltage output function is the right choice when a precision source of DC voltage is needed. Its bipolar output delivers up to ±12 V with 10 mV resolution and up to 35 mA of current.

Sensor embedded presets

Automotive Sensor Simulator with built-in preset configurations for simulation of CKP Inductive, CKP Hall Effect, Lambda sensor Zirconia, Lambda sensor Titania and Knock Sensor. You can disconnect sensor from the vehicle harness, inject the signal in the harness and watch the scope to see if the PCM responds positively.

AutoSim Pro

What a great piece of kit. No more swapnostics with sensors based on a DTC. Sensor simulation effectively allows the problem resolution more effective.
