Abstract: In order to test high density multicore cable more conveniently and overcome a difficulty on insitu testing of high density multicore cable,a multichannel detector was designed. Detecting electric circuit extended multichannel with ADG706,each channel accomplished data communication and sampling with time division multiplexing. The channel settling time and the max sampling rate were calculated. The hardware and software designing illustration were given and communication interface were discussed. The applications showed that this detector could be applied to high density multicore cable for undamaged and unmoved test. Test omission could be avoided and test accuracy could be improved with the detector.

Key words: multichannel, multicore cable, detection, ADG706
