High precision analog and digital testing board

Complete ECU testing, especially hardware in the loop testing, requires not only connecting the communication network to the testing system, but also connecting digital and analog signal interfaces. The high-precision analog and digital testing boards developed by Fengchuan Power can greatly simplify the setup of testing benches and HIL testing systems, and improve the efficiency of system construction and testing. The analog board supports stable output of positive and negative voltages ranging from -12V to+12V, while the digital board supports output of the ABZ three channel correlated signal of the analog magnetic encoder.
