2-Channel Digital Signal Generation 
The DM91-102G offers dual-channel digital signal generation which is ideal for automotive diagnostics and testing. 
It provides precise control over signal output for reliable performance in complex electrical systems.
Integrated CAN Data Function Equipped with CAN data functionality
Supports modern vehicle communication protocols and enables accurate simulation of CAN bus signals for advanced troubleshooting and repair tasks.

Signal characteristics can be adjusted in real time: the waveform, amplitude, frequency and number of missing teeth can be adjusted at will in the signal output department, which greatly facilitates the fault determination.

Channel: Dual Channel
Supports USB Storage Device: Connecting with PC or transferring test data to PC
