For ATE you need to drive the supply from software. The N35500 ships with LAN/RS232/RS485/CAN and speaks SCPI, Modbus-RTU and CANopen, so it slots into existing racks and sequencers.
Pick the protocol to match the bench
SCPI for instrument-style scripting over LAN; Modbus-RTU for PLC and industrial integration; CANopen for automotive and embedded test. Sequences, waveforms and battery/PV profiles all run under remote control.
