Plug-in Modules Overview
The Agilent 3499A/B/C mainframes support multiple Plug-in modules,
including all the existing 3488A modules (4447XX modules), as well as
several new ones (N22XXX modules). Based on their functions, the
modules can be divided into five classes:
•
Multiplexer (MUX) modules
•
General Purpose Relay (GP) modules
•
Matrix modules
•
Digital I/O (DIO) modules
•
Multifunction modules
•
Optical Modules
Note Refer to the “Plug-in Modules” chapter on page 173 for the details of the
individual Plug-in modules.
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.
