Note: The 30 dB directional coupler is not used
with the Cybertest test set. The TX cable is
connected directly to the Cybertest test set.
A 10dB attenuator must be used with the short test
cable for cable calibration with the CyberTest test
set. The 10dB attenuator is used only for the cable
calibration procedure, not with the test cables for
TX calibration and ATP tests.
