The Agilent 34980A is an eight-slot mainframe that includes an optional built-in 6 ½ digit DMM. Choose from 19 optional plug-in modules that offer a broad range of functionality that includes DC to 20 GHz switching, counter/totalizer, digital I/O with pattern capabilities, and D/A converters - in one compact, high-performance modular platform.

High-performance unit provides low-cost alternative to PXI and VXI switch and measurement platforms

If you use automated test equipment for design validation or manufacturing, you now have a cost-effective alternative to PXI and VXI test-system platforms. The 34980A multifunction switch/measure unit provides comparable functionality that is much easier to use than PXI and VXI and costs less. The 34980A helps you lower your cost of test and accelerate your test-system integration and development.

The 34980A handles system switching up to 20 GHz and provides basic measurements and system control. It also offers DMM measurements, counter/totalizer functionality, digital I/O with pattern capabilities, and analog out-puts 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.

Flexible switching, measurements, and system control

The 34980A accommodates up to 8 plug-in modules to give you the flexibility you need. Choose from 19different modules to define 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 with no external signal conditioning required. Choose between different switch types and topologies with frequency ranges from DC to 20 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.

Use the 34980A to route individual signals or monitor multiple signals over a specified period of time—monitor a single channel or multiple channels, set alarms, and identify irregularities.

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.

Optimized for test systems

The 34980A has the performance you need for medium- to high-density switching/measurement applications such as design verification, 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 DMM and achieve optimal throughput on switch closure time. Or, if you prefer, you can easily connect to external instruments such as DMMs, scopes, power supplies, and more. What’s more, with the built-in Ethernet interface, you can control the 34980A and collect data from remote locations.

The rugged instrument comes with a variety of system-ready features:

Web browser interface shows settings at a glance and provides remote access and control

Self-guiding front panel to configure, troubleshoot or view data

Low EMI and efficient system cooling

Heavy-duty cabling and connection options

Rack mount options

Relay counters help predict end-of-life

In-rack calibration for reduced maintenance time

DMM measurement accuracies include the switch for simple calculations

Make system connections easily and quickly with simple, reliable connection options:

Built-in Ethernet, USB 2.0, and GPIB connectivity

Low-cost, standard 50- or 78-pinDsub connectors and cables

Detachable terminal blocks with strain relief

Mass interconnect solutions

In addition, the 34980A comes with Agilent E2094N IO Libraries Suite 14.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 DMM, 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 DMM and use the other three buses for module extensions or additional signal routing between modules, reducing your wiring needs.

You can define 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. 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.
