The 9130B Series triple output linear
programmable DC power supplies feature isolated
outputs that can be adjusted independently or
combined in series or parallel to output higher
voltage or current. Additionally, these supplies
can operate in tracking mode with
user-configurable ratios between channels.
The front panel keys and rotary knob with
convenient cursors let users quickly set voltage
and current values. Up to 36 different instrument
settings can be saved and recalled. The power-on
state of the outputs can also be configured.
For remote control, the standard USB (USBTMC-
compliant), RS232, and GPIB interfaces
Features
■Three independent and electrically isolated
outputs
■Displays voltage and current settings for all
three channels simultaneously
■Low noise, linear regulation
■High programming and readback resolution of
1 mV / 1 mA
■Series and parallel modes combine channels to
increase the output voltage or current
■Tracking mode allows users to set up channels
to maintain a programmed ratio
■Fully programmable channels with Output
On/Off control
■Store and recall up to 36 instrument settings
■Remote sense
■Timer-controlled output function adjustable
from 0.1 – 99999.9 s
■Standard USB (USBTMC-compliant), RS232,
and GPIB interfaces supporting SCPI
commands for remote control
■NI certified LabVIEW driver and softpanel for
remote control, test sequence generation, and
datalogging available
■Overvoltage (OVP) and overtemperature (OTP)
protection including keylock function
■Compact 19” half-rack form factor allows for
side-by-side rack mounting of two units

supporting SCPI commands can be used to
remotely control the power supplies via a PC.
Alternatively, users can control the power supply,
execute test sequences or log measurements
using the provided PC software application. This
software also integrates with Data Dashboard for
LabVIEW apps enabling iOS, Android, or
Windows 8 compatible tablets or smartphones to
remotely monitor select measurement indicators.
These power supplies are suitable for a wide
range of applications including production
testing, telecommunications, R&D, electronic
service, and labs.

Flexible operation
Combined series mode
Channels 1 and 2 can be wired in series to
increase the voltage. Selecting Series Combined
Mode provides convenient metering of the
channels connected in series.
Test system integration
These power supplies offer standard USB, RS-232, and GPIB interfaces to facilitate test system
development and integration. The 9130B Series supports SCPI-compliant protocols and come with
LabVIEW™ drivers.
Application software
PC software is provided for front panel emulation, generating and executing test sequences or logging
measurement data without the need to write source code.
■ Remote monitoring on iOS, Android, or Windows 8 compatible tablets or smartphones via NI Data
Dashboard for LabVIEW apps.
■ Log voltage, current, and power values of each channel as well as timestamp, CV/CC mode, and output
status.
■ Quickly develop a custom dashboard with indicators, charts, or gauges to monitor your power supply.
■ Create an unlimited number of external list files to be executed from PC memory. Save and recall list
files to/from the PC.
Channels 1 and 2, 2 and 3, or All channels can
be wired in parallel to increase the current.
Selecting Parallel Combined Mode provides
convenient metering of the channels connected
in parallel.

Tracking mode
Tracking mode can be used to simplify
adjustments across multiple channels by
maintaining a user-defined ratio between outputs.
Tracking mode can be set on channels 1 and 2, 2
and 3, or All channels.
