Multiple GS820s can be connected as shown below and used as a multi-channel source measure unit. The master-slave feature allows the program data of all connected channels to be set and collected by simply accessing the master unit. The master unit (1) distributes the source data to the slave units or (2) collects and merges the measured data of all slave units. Complete synchronization of all channels can be achieved by connecting the exclusive trigger signal line.

The zero generation function of the GS820 generates zero voltage or current as well as controls the current/voltage limiter to limit the load current. The GS820 stops applying the voltage or supplying the current to the load in the zero generation state allowing the DUT to be disconnected with the output relay turned ON. This function avoids the problems of chattering and contact life of the output relay and reduces the time for turning ON/OFF the output.
