Keysight Technologies, Inc. IO Libraries Suite enables you to quickly establish an error-free connection
between your PC and instruments—regardless of vendor. The IO Libraries provide robust instrument
control and enables you to work with the software development environment you choose.
The 34980A provides four 2-wire internal analog buses for easy signal routing. 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 which can reduce wiring complexity.
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 create. 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, other events,
and control when to begin or end an acquisition.
Measurements you can trust
Get proven performance from Keysight instruments, with the resolution, repeatability, speed, and
accuracy you’ve come to expect.
The 34980A offers built-in signal conditioning and modular flexibility. When you use it with the internal
DMM, you can configure each channel independently for the measurements you choose. It includes a
variety of features that give you confidence in your measurements:
• 6½ digits of resolution with .004% of accuracy with DC voltage measurements
• Alarms per channel—high limit, low limit, or both
• Math functions—use Mx+B for custom linear conversions and converting raw inputs
• Built-in thermocouple reference for temperature measurements (34921T)
• Time-stamped readings
• Add more formulas with BenchVue DAQ
The integrated DMM is mounted inside the mainframe and does not consume any of the eight user-
available slots. You can access the DMM through any switch module that connects to the analog bus, or
directly from the analog bus connector on the rear of the mainframe. The internal DMM gives you the
flexibility to measure 11 types of inputs:
