Instrument Description
2-16
2
INTERCEPTOR 147 2 Mbit/s and Data Analyzer
Terminate mode also provides automatic cable equalization
(such as when you are testing on the network, or line, side
of multiplexers, NTE, or NTUs), as illustrated below.
BRIDGE
Use BRIDGE mode to monitor a 2 Mbit/s signal (such as
when you are performing in-service, or non-intrusive,
tests) from a monitor point that is not equipped with
isolation resistors (as illustrated below). With BRIDGE
mode, the test instrument provides an input impedance of
greater than 1000
Ω
and provides automatic cable
equalization so that the testing will not affect the circuit
under test.
2.9 MISCELLANEOUS CONTROLS AND
