40/42-204-001 Single Channel 1000Base-T1
Fault Insertion Switch Schematic Diagram
The 40-204 (PXI) and 42-204 (PXIe) are designed
to simulate common faults on high-speed two wire
communication interfaces such as 1000Base-T1. They
support 1 or 2-channels of two wire serial interfaces. Each
channel pair can be looped out to external equipment or
the switches can be used simulate a channel open fault.
Using the fault bus, switches can simulate a short between
both wires or a short to one of two externally applied fault
conditions – such as battery supply or ground - via two
fault buses.
Each channel can carry up to 0.8 A and is rated up to 200 V
between wire pairs. The wire pairs have controlled
transmission line impedance suited to most differential

signalling systems, including high-speed 1000Base-T1,
the fault buses are capable of carrying 0.8 A and also
have controlled transmission line impedance. The front
panel signal connectors are easy to use MMCX which are
fully supported by our range of connector accessories.
The module uses high quality electro-mechanical relays
designed for high frequency application with long service
life.
Differential Bus Switching
We also offer the 40-736 and 40-737 multiplexers which
are suitable for switching Ethernet, USB and other serial
communications signals.
