Serial interface connector for RS232 or
USB communication.
Model 9123A also supports control via
GPIB interface.
Remote Sense and digital
port functionality
The 9120 series uses 4mm sheathed banana
jacks that accept sheathed or shrouded banana
plugs and meet the latest international safety
standards.
Extra Features
The 9120 series’ digital port offers a variety of
configurations. The port can operate in Digital I/O,
external Trigger and DFI/RI (Discrete Fault
Indicator/Remote Inhibit) mode. The RI feature can
be used for turning several power supplies On/Off
simultaneously. External triggering can be used in
combination with List mode.
The included Application Software supports front
panel emulation and allows users to generate
simple test sequences without the need to write
source code.
Additionally, the power supply comes with a built-in
51/2 digit DVM and high resolution milliohm meter
supporting 4 wire measurements.
R
emote Interface
The power supplies can be remotely controlled
from any PC with USB or RS232 interface,
a
llowing the user to program and monitor all
parameters through easy to use SCPI commands.
The power supplies come with a RS232 to TTL
s
erial converter cable and a USB to TTL serial
converter cable. Additionally, model 9123A can
be controlled via GPIB interface and includes a
G
PIB to TTL conversion adapter cable.
