Agilent 34980A Multifunction Switch/Measure Unit

New 34980A Multifunction Switch/Measure Unit is a compact, economical one-box solution for medium to high-density switch/measure applications in design verification, automated test and data acquisition. The 34980A is an expandable and reconfigurable platform with 19 mix and match switch measurement modules.

Key Features and Specifications

Broad offering of modules
- 8-slots with integrated 6 ½ digital DMM
- 19 plug-in modules with LF/RF/uW switch, DIO, D/A converter, and counter
- 560 2-wire mux or 1024 2-wire matrix cross-points in one mainframe
Ease of integration
- Standard LAN, USB, GPIB connectivity to PC
- Standard cables, terminal cards or mass interconnect
Low cost
- Priced up to 40% less than comparable module solutions in VXI or PXI

The 34980A includes a built-in graphical web interface that 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.

View and modify instrument setup
Open, close, or monitor switches
Setup and initiate scans
Send SCPI commands
Define and execute switch sequences
View error queue
Get status reports on relay counts, firmware revisions, and more

The internal DMM is mounted inside the mainframe and does not consume any of the eight user-available slots. It gives you the flexibility to measure 11 types of inputs:

Temperature with thermocouples, RTDs, or thermistors (with 34921A)
DC and AC voltage
2- and 4-wire resistance
Frequency and period
DC and AC current

Modules at a Glance

The 34980A mainframe holds up to eight plug-in modules. Mix and match them to create a custom system to meet your switching and system control needs. You can easily add or replace modules as your needs change.
