Section 4. Remote Operation
Introduction
The switches and connector on the rear panel of the power supply allow you to
program the supply with an analog device or to readback analog signals.
Remote
Digital
Programming
You can operate the power supply from a computer if you have the optional GPIB or
RS-232 interface card installed. Refer to the separate interface manual for all setup
and operation instructions for remote digital programming.
Remote Analog Programming of Output Voltage and Current Limit
Remote analog programming allows control of the power supply’s output voltage
and output current limit to shift from local operation at the front panel voltage and
current controls to external analog input sources. As you vary the programming
source, the power supply’s output varies proportionally over its output range.
Using remote analog programming requires that you make connections to the J210
connector on the power supply’s rear panel. See “Rear Panel J210 Connector” on
page 15. To reduce radiated emissions, add a ferrite block to the wires that go to the
J210 connector. The 1 inch square ferrite block with built in housing clip is packaged
and shipped with the power supply.
