Glossary 129
Exception
An error that occurs during testing. For example, if an instrument that is supposed to make a
measurement “times out” before returning a reading, an exception has occurred.
Expander Block
Provides various configurations of screw terminals. There are two types of expander blocks currently
used on the TS-5400 mass interconnect:
• 4 Terminal Expander Block: This is a four-screw terminal block. All four connection
points are common.
• 1,1,2 Expander Block: This is a four screw terminal block, but only two screws are con-
nected together. Each of the other two screws acts as an isolated connection point.
F
Factory Default Algorithm
A systematic instrument and ICA configuration of the Agilent TS-5400 used by Agilent for shipping
systems that do not have a customer specified instrument configuration. This allows the re-use of system
topology data that describes the mapping of the system-ICA connections.
Factory Default Configuration
Standardized instrument locations, switch and jumper settings, and ICA connector locations used by the
factory when assembling a TS-5400 system. The default configuration differs between a one- and two-
mainframe system.
Fixture
An interface consisting of; an Interface Test Adapter (ITA) fixture frame, general purpose connectors,
high-power coax connectors, expander blocks, blank slot covers, and wires to a DUT connector. This
interface connects to the matching Interface Connector Assembly (ICA) of the mass interconnect. See
ITA.
Fixture Receiver
See ICA.
