Fault Insertion Switch Schematic Diagram
The 40-203 (PXI) and 42-203 (PXIe) are designed to simulate
common faults on high-speed two wire communication
interfaces such as 1000Base-T1. They support up to 6 channels
of two wire serial interfaces. Each channel pair can simulate
an open fault in either or both wires, and using the fault bus
switches can simulate short between both wires or a short to
one of two externally applied fault connections – 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 reed relays designed
for high frequency application with a long service life.
