Abstract :
This paper introduces a kind of multi-channel parallel testing system. This system could provide five kinds of different interface and produce 145 channels parallel driving source. Concurrently the system could acquire a channel of PCM code and monitor the code in real time. AD5628 DAC and OPA4234 operational amplifier is used to realize output voltage in the range of 0~31V.And the Export accuracy of 0.1 per cent is achieved.
