MUX Modules
A MUX (multiplexer) module switches one signal to multiple DUTs
(devices under test), or multiple signals to one device, one at a time.
Example applications include capacitor leakage, connector/switch
contact, and insulation resistance test systems. To expand switching
capacity or build special configurations, the multiplexer switching
modules can also be used with matrix or other switching modules. The
figure below shows a simple 1 x 4 Multiplexer.
Simple Multiplexer Switching
Multiplexers are available in several types:
•
One-Wire (Single-Ended) Multiplexer for common LO measurements
•
Two-Wire Multiplexer for floating measurements
•
Four-Wire Multiplexer for resistance and RTD measurements
•
Very High Frequency (VHF) / Microwave Multiplexer for switching
frequencies up to microwave (26.5 GHz).
The table on the next page lists the available MUX modules.
