Keysight 34980A/001 – Multifunction Switch / Measure Unit Mainframe (without Internal DMM)

The 34980A multifunction switch/measure unit provides functionality that is easy to set up and use with a fast startup time. The 34980A helps you lower your test cost and accelerate your test-system integration and development.

The 34980A handles system switching up to 26.5 GHz and provides basic measurements and system control. It also offers DMM 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 Keysight 34980A/001 is a 34980A with option 001. Option 001 removes the 6.5 digit internal DMM.

The 34980A accommodates up to 8 plug-in modules to give you the flexibility you need. Choose from over 20 different 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 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.

1. The On/Standby switch is used to toggle the 34980A between On and Standby modes only. To turn the unit off, remove the power cord.

2. The Utility key accesses menus to configure Remote I/O (LAN, GPIB, and USB) operation, set Date and Time, and configure other system-related instrument parameters.

3. The Store/Recall key allows you to save and recall up to six instrument setups.

4. Control keys directly control module actions.

5. The number keypad is used for entering numerical characters.

6. The exponent entry key is used to enter the exponent during a numerical entry.

7. The Cancel key exits any menu without saving changes.

8. Arrow keys move the cursor position in an entry.

9. The knob provides for entry of alphanumeric characters, selecting slots or channels, and navigating menus.

10. The Enter key steps you through a menu or saves number entries.

11. Running a program puts the display into “remote” and disables the front panel keys. Local takes you out of “remote” mode and enables the front panel keys.

12. Configure keys select functions and set function parameters.

13. Measure keys execute and monitor measurements. Depending on which measurement key you use, you can have complete/direct control over the switching and measurement operation, or you can have the 34980A automatically control these to capture the desired data.

1. Access to Analog Buses (shown with removable cover installed)
