The 34972A LXI Data Acquisition/Switch Unit is an LXI version of the 34970A. It replaces the GPIB and RS-232 interfaces with modern connectivity - LAN and USB - for a direct connection to your PC or Laptop.
Keysight took the measurement engine from their best-selling benchtop DMM and embedded it inside a 3-slot cardcage. You get the benefit of proven Agilent measurement performance, universal inputs with built-in signal conditioning, and modular flexibility, all in a low-cost, compact data acquisition package. The 34970A features 6-1/2 digits (22 bits) of resolution, 0.004% basic dcV accuracy, and ultra-low reading noise. Combine that with scan rates of up to 250 channels/sec, and you've got the speed and accuracy you need to get the job done right the first time.
The 34980A is an eight-slot mainframe that has an optional built-in 6.5 digit DMM with your choice of 19 different plug-in modules. These include switching from DC to 20 GHz, digital I/O, D/A converters, and counter/totalizer functionality. One mainframe can accommodate up to 560 2-wire multiplexer channels or 1024 2-wire matrix cross points. The 34980A also includes USB, Ethernet, and GPIB as standard interfaces to the PC.
The Keysight L4400 Series LXI instruments are high-performance LXI Class C compliant instruments that encompass all benefits of LXI with an Ethernet connection, instrument Web server, standard software drivers and more. With their small size and Ethernet connectivity, these instruments are easily placed anywhere on the network.
