Abstract:
1. An apparatus including a system for enabling testing a data link of a data packet signal transceiver device under test (DUT), comprising: a reference device signal path to convey a RX data packet signal originating from a reference device for reception by a DUT and convey a TX data packet signal originating from said DUT for reception by said reference device; a DUT signal path to convey said RX data packet signal originating from said reference device for reception by said DUT and convey said TX data packet signal originating from said DUT for reception by said reference device; and signal attenuation circuitry coupled between said reference device signal path and said DUT signal path, and responsive to one or more control signals by conveying at least a portion of said RX data packet signal with a RX signal attenuation and conveying at least a portion of said TX data packet signal with a TX signal attenuation, wherein said RX signal attenuation and said TX signal attenuation are unequal, and said signal attenuation circuitry is responsive to said one or more control signals by attenuating said RX data packet signal with said RX signal attenuation during at least a portion of a RX time interval and attenuating said TX data packet signal with said TX signal attenuation during at least a portion of a TX time interval.
