Introduction to your PPS 2 - 3REAR PANELThe rear panel contains connectors for the line power input, the output channel(s), the trigger lines, and the GPIB (IEEE 488) interface. A fan provides forced cooling of each output channel. The line power input module also contains the line fuses, line filter, and the power switch.For remote control, a GPIB (IEEE 488) connector for use with a GPIB controller is provided.Three SMB connectors for START, STEP, and READY are provided for external triggering of the step mode and recalling stored instrument settings.
