5.4 OPERATING FEATURES

Your programmable power supply is equipped with a GPIB interface, which
conforms to the IEEE-488.2 standard and the SCPI protocol (Standard
Commands for Programmable Instruments). The power supply can be
programmed to operate in a remotely controlled instrumentation system via the
GPIB.
You can use each output channel of the power supply as a constant voltage
source (CV mode), as a constant current source (CC mode), or as a constant
current sink (PM283x only). There are three instrument types available:
• single output channel power supply
• dual output channel power supply
• triple output channel power supply
A channel can have various output voltage and output current ratings.
The operating structure and operating principles are identical for each instrument
type and for each output channel.
The following features have been implemented in each power supply:
• Power on self-test and diagnostics routines.
• Readback capability of the measured voltage and current of each output
channel.
• Each output channel offers the ability to sense locally or remotely. For remote
sensing, the sense terminals (+S and -S) must be connected to the load
instead of the +V and -V output terminals; then the programmed voltage (V
is guaranteed to be across the load, in spite of the voltage drop in the wires to
the load.
• A nonvolatile memory (battery backed up). This enables you to:
- store and recall voltage and current settings of all output channels
(refer to section 5.5.4 "Store/Recall function")
- save and recall the front panel settings (refer to the common
commands
In this way, stored settings can be recalled, even after a long period of power
off.
