The VX1000 family is a modular measurement and calibration solution from Vector that can be used in the engine compartment, on test benches, and in the laboratory. The system acts as an interface between the ECU and a measurement and calibration tool such as CANape. For data throughput of up to 5 MByte/s, data is accessed using microcontroller-specific data trace or debug interfaces. The VX1000 system connects directly to a PC, and the solution features calibration and bypassing functions with short latency times and flash programming of expired ECUs. Other features include minimum event cycle of less than 15 ms, data acquisition event triggering by a single memory write access, minor modification of ECU codes and minimal influence on execution times, read/write access to ECU internal memory, and 100 Mbit/s ethernet connection to a PC for configuration and software updates.
