Can provide a variety of customised test products for hardware and software debugging in the development stage. Hardware / software / system development process of various types of debugging load box, burn-in tools, custom development of special signal simulators (Sent, wheel speed, rotary, LVDS to HDMI, etc.); load box can provide the controller peripheral excitation signals and loads, which excitation signals are generally self-developed integrated multi-channel signal generator generated. Hardware debugging load box inside the real load or parameters close to the analogue load; software debugging load box inside the analogue load using low-power; EMC test load box using a shielded box.
