5.4 OPERATING FEATURES
Your pro
rammable power supply is equipped with a GPIB interface, which
conforms to the IEEE-488.2 standard and the SCPI protocol (Standard
Commands for Pro
rammable Instruments). The power supply can be
pro
rammed to operate in a remotely controlled instrumentation system via the
GPIB.
You can use each output channel of the power supply as a constant volta
e
source (CV mode), as a constant current source (CC mode), or as a constant
current sink (PM283x only). There are three instrument types available:
•sin
le output channel power supply
• dual output channel power supply
• triple output channel power supply
A channel can have various output volta
e and output current ratin
s.
The operatin
structure and operatin
principles are identical for each instrument
type and for each output channel.
The followin
features have been implemented in each power supply:
• Power on self-test and dia
nostics routines.
• Readback capability of the measured volta
e and current of each output
channel.
• Each output channel offers the ability to sense locally or remotely. For remote
sensin
, the sense terminals (+S and -S) must be connected to the load
instead of the +V and -V output terminals; then the pro
rammed volta
e (V
set
)
is
uaranteed to be across the load, in spite of the volta
e drop in the wires to
the load.
• A nonvolatile memory (battery backed up). This enables you to:
- store and recall volta
e and current settin
s of all output channels
(refer to section 5.5.4 "Store/Recall function")
- save and recall the front panel settin
s (refer to the common
commands
*
SAV and
*
RCL).
In this way, stored settin
s can be recalled, even after a lon
period of power
off.
