The 9171B programmable DC power supplies offer industry leading performance, designed to meet the most demanding applications in R&D, design verification, and production test. All nine models deliver clean, stable and precise output power due to their exceptionally low ripple and noise, low temperature coefficient, excellent regulation, and fast transient response time characteristics.

These power supplies are well suited for both bench use and ATE applications. For bench use, these power supplies offer an intuitive user interface with a full numerical keypad for convenient data entry. R&D and design engineers will appreciate front panel output and remote sense terminals (available on select models). Free application software is provided for remote control without the need for any computer programming. USB and optional GPIB/LAN interfaces combined with a fast transient response and command processing time, make this series ideal for ATE applications.

In addition to a full numerical keypad for convenient data entry, this series also provides unique features not typically found in comparable power sources, such as LED test modes, modular interface card slots, automatic range selection, and an optional 8-bit bidirectional digital I/O interface.

To protect your DUT (device under test), the 9170B/9180B series provides safety options such as OVP, OCP, and a key-lock feature to prevent accidental change of parameters that might damage your DUT. Built for reliability, the supplies are also backed by a 3-year warranty.

Modular interface card slots
Only buy what you need, when you need it. Pick and choose from up to 4 different types of interface cards to install at time of purchase or upgrade later. Interface card options include: LAN and GPIB, Digital I/O and Analog Control, RS485, or RS232. Installation is quick and easy and does not require opening the instrument case (does not void warranty).

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 (Requires card option DR1DIO or DR2DIO)
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.

  • Create, save, and load program lists
  • View output characteristic curves and export data to a file
  • Pass/Fail test monitors maximum and minimum voltage and current values over a specified period of time

Web server interface (Requires card option DRGL)
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 (Requires card option DRGL)
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 (Requires card option DRRS485)
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.

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.

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. Powering LEDs with conventional power supplies will potentially cause permanent damage to the UUT or limit its lifespan due to 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.

Low current mode (Low current mode for high voltage models 9184 and 9185 only)
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.
