Abstract
An interfacing device having two operational amplifiers that have been manufactured on the same IC die have high-impedance input terminals connected directly to the two conductors of a local area network digital transmission line so as not to load or otherwise upset the impedance or other parameters of the transmission line. The output terminals of the operational amplifiers are connected to and match the input impedance of a digital transmission protocol analyzer. The gain of the operational amplifiers is arranged so as to replicate at the input of the analyzer the signals appearing on the local area network transmission line.
