Programmable Dual-Range DC Power Supplies
9170B & 9180B series
External control and programming
Versatile connectivity
These power supplies offer SCPI IEEE488.2 compatible standard USB, optional
GPIB and LAN interfaces, and an optional 8-bit digital I/O and analog control
card to facilitate test system development and integration.
Test sequence execution in list mode
The list mode feature allows users to download a list of commands to the
power supply’s internal memory and execute them. A total of 150 steps can
be allocated to one of 10 internal memory locations. The test sequence can be
programmed from the front panel, remotely through the included application
software, or via the USB, GPIB, or LAN interfaces using SCPI commands. Each
step’s voltage, current, and duration parameters can be set, with sequences
configured for single or repeated execution.
External analog programming interface
(1)
The power supplies’ output voltage and current can be controlled by either
external analog voltage or resistance. Use a 0-5 V or 0-10 V external DC
voltage source, or 0-5 kΩ variable resistor to control the output from zero to
full scale.
Application software
Create test sequences for execution in list mode via the GPIB or USB interface
using the included PC software.

The 9170B/9180B series power supplies with the GPIB/LAN interface installed
provide a built-in Web server that allows users to configure, control, or monitor
the basic settings of the power supply from a remote computer using a Java-
enabled Web browser. Connect to the user-defined IP address to view the web
control page. SCPI commands can also be sent through the Web server interface.

Telnet interface
(2)
Power supplies can be controlled with SCPI commands via a Telnet connection
over the Ethernet interface. Any computer with a Telnet client can be used to
control the power supply.
Multi-unit control
(3)
In multi-unit control mode, up to 31 units can be daisy chained via the RS485
interface for synchronization purposes and controlled from one master unit via
the USB, GPIB, or LAN interface.

Programmable Dual-Range DC Power Supplies
9170B & 9180B series
Two power supplies in one
The 9170B/9180B series provide a unique dual
range feature that offers the best of both worlds
by supplying two different ranges. Users can
select between high and low range operation for
either more voltage or more current depending
on your application, avoiding the higher cost of
buying more power than necessary.
9170B/9180B Series Operating Range
Test modes for LED and other special applications
To address the growing LED market, the 9170B/9180B series design incorporates special LED test modes for efficient and safe electrical tests of LED panels. Power-
ing LEDs with conventional power supplies will potentially cause permanent damage to the UUT or limit its lifespan. This damage is caused by the excessive inrush
current at power up and the non-linear characteristics of the LED’s I-V curve. These power supplies feature two distinct operating modes suitable for LED testing in a
manufacturing or R&D environment and other special applications requiring a controlled rise time at power up without generating any inrush current.
LED mode
With LED mode active, inrush current will be eliminated or minimized to protect the UUT.
Inrush current
Output ON
Output ON
LED mode ON
LED mode OFF
Current flow during power up with LED mode enabled
Example LED test setup
Low current mode*
This unique function enables the power supply to
minimize the voltage rise time in a controlled
manner. This mode is used when operating at a
low current (< 1 A) and quick transitions from a
high-to-low or low-to-high voltage are needed.
Low current mode OFF
Low current mode ON
Voltage rise time with and without low current mode enabled
* Low current mode for high voltage models 9184B and 9185B only.
