28000 Analog Signal Conditioning System

The new standard for the world's most discriminating test labs.

The 28000 System makes it easy to manage a test with up to 256 channels of fully programmable transducer conditioning. Choose a mix of bridge, charge, IEPE w/TEDS, voltage (filter/amplifier), strain, thermocouple, RTD/ potentiometer, frequency, or other transducers.

Precision PF-1U-FA Multi-Channel Programmable Filter/Amplifier System

Exceptional desktop performance at low cost.

Ideal for conditioning low-level voltage inputs in front of high-resolution digital data acquisition systems. Fully programmable 8-channel and 16-channel configurations are available, both offering a choice of either 4- or 8-pole low-pass filters with programmable gain up to 8,192.

464kB High Density Programmable
Switch Matrix

Computer controlled analog signal switching replaces tedious manual patch panels.

The 464kB is a reliable solid-state switch matrix system that provides computer-controlled connection between 256 inputs and 256 outputs, all in a single mainframe. Save time and reduce errors on test system setup. Download switch configurations from the host computer over the network. Built-in self-test with fault diagnostics.
