Text Fixtures
Telecommunications signals require specific load impedance for compliance testing to be accurate. The
twisted pair standards require 100 Ohm and 120 Ohm terminations, and the other standards require 75 Ohm
terminations. A set of adapters (test fixtures) for this purpose is available from Teledyne LeCroy (part number
TF-ET).
NOTE: These adapters require an additional LPA-BNC-ProLink adapter if they are being used with a
WaveMaster, LabMaster, or SDA.
