The Agilent/Keysight Technologies 34980A Multifunction Switch/Measure Mainframe, Refurbished handles system switching up to 26.5 GHz and provides basic measurements and system control. It also offers Digital Multimeter measurements, counter/ totalizer functionality, digital I/O with pattern capabilities, and analog outputs with basic waveforms- all in one low-cost, compact box. And with its standard connectors and software drivers, computer-standard I/O, and Web browser interface, the 34980A easily integrates into electronic functional test and data acquisition systems.

The 34980A accommodates up to 8 plug-in modules to give you the flexibility you need. Choose from 21 different modules to deine your own configuration. You can buy what you need now and add to it or reconfigure it as your requirements change.

Whether you are measuring temperature, AC or DC voltage, resistance, frequency, current, or custom measurements, the 34980A offers the functionality you need in a single box. Switch in different measurements with high-performance signal switching up to 300V with no external signal conditioning required. Choose between different switch types and topologies with frequency ranges from DC to 26.5 GHz. The 34980A offers high-density multiplexers for scanning multiple channels, matrices for connecting multiple points at one time, and general purpose switches for simple control and high power needs.

The 34980A offers flexible choices for system control. You can control external devices such as microwave switches, attenuators, solenoids, and power relays. Or use the digital inputs to sense limit-switch and digital-bus status.

The 34980A has the performance you need for medium- to high-density switching/measurement applications such as design veriication, functional test and data acquisition. Your signals are switched to the right measurement device without compromising signal integrity. Switch your signals to the optional internal Digital Multimeter and achieve optimal throughput on switch closure time. Or, if you prefer, you can easily connect to external instruments such as Digital Multimeters, scopes, power supplies, and more. What's more, with the built-in Ethernet interface, you can control the 34980A and collect data from anywhere on the network. For a complete modular solution, use the 34980A together with PXI modular products when more capability is required.

In addition, the 34980A comes with Keysight Technologies, Inc. IO Libraries Suite.

Quickly establish an error-free connection between your PC and instruments-regardless of vendor. The IO Libraries provide robust instrument control and work with the software development environment you choose.

Easier signal routing with four 2-wire internal analog buses. You can route your measurements directly to the internal Digital Multimeter, or you can connect to external instruments through the analog bus connector on the rear of the mainframe. And since you have four 2-wire buses, you can dedicate one bus for use with the internal Digital Multimeter and use the other three buses for module extensions or additional signal routing between modules, reducing your wiring needs.

You can define up to 500 switch sequences to control complex signal routing and the order of switch closures. Assign a sequence, give it a name and then execute it with the name you created. Switch sequences are downloaded and stored in the instrument for ease of programming and increased throughput.

External trigger capabilities make it easy for you to time and synchronize measurements and other events. This can help you determine when to begin or end an acquisition.

The 34980A offers built-in signal conditioning and modular flexibility. When you use it with the internal Digital Multimeter, you can configure each channel independently for the measurements you choose.

The integrated Digital Multimeter is mounted inside the mainframe and does not consume any of the eight user-available slots. You can access the Digital Multimeter through any switch module that connects to the analog bus, or directly from the analog bus connector on the rear of the mainframe.

You can control the Digital Multimeter directly, or configure it to work in conjunction with the switches. Each switch channel can be configured independently for measurement functions, scale factors and alarm limits. Advanced measurement features such as offset compensation, variable integration time, and delay are also selectable on a per-channel basis.

The Digital Multimeter inputs are shielded and optically isolated from the 34980A's earth-referenced circuitry and computer interface, and as a result, you get up to 300 V of input isolation. This is important for reducing ground-loops and common-mode voltage errors associated with long wiring runs and loating sources.

Simple Digital Multimeter calibration is accomplished with just the analog bus connection on the rear panel of the mainframe. You don't need to remove the mainframe from the rack or dedicate a channel for calibration.

Standard Ethernet, USB and GPIB interfaces are included in every mainframe. Use one of the built-in interfaces that is already available in your computer, or if you prefer, GPIB is still available.

The built-in Web browser interface provides remote access and control of the instrument via a Java-enabled browser such as Internet Explorer. Using the Web interface, you can set up, troubleshoot, and maintain your system remotely.

Additionally, since the Web interface is built into the instrument, you can access it on any operating system that supports the Web browser without having to install any special software. Password protection and LAN lock out are also provided to limit access.The Web interface makes it easy to set up, troubleshoot and maintain your system remotely.
