The MR8740T (MR8740-50) is rack-mountable data acquisition system that delivers high-speed, multi-channel measurements over maximum of 108 channels. Generate simulated signals and record at the same time using plug-and-play input units, making the waveform recorder ideal for evaluating multi-signal devices such as vehicle electronic control units (ECU).

Key Features

Note: A special option such as an input unit is required for the main unit. Please purchase various common options such as input cord separately.


FEATURES

ECU Testing
ECUs are connected to a large number and wide variety of sensors. The MR8740T can be installed with signal generation unit to simulate these sensors. By measuring the simulation results with a measurement unit at the same time, you can perform all steps from signal generation to measurement with a single device. The U8794 VIR GENERATOR UNIT also offers resistance output to enable thermistor circuit testing.

Ideal for testing that requires simulated signals
When used as an ECU testing device, generate simulated signals from various sensors, which is indispensable for testing electronic parts and maintaining equipment. Record signals captured by various sensors to identify air flow, throttle, torque, speed, vibration, humidity, etc.
