Patent ID: 7317318

Claim:
A method of operating a test instrument to compensate for near end cross talk (NEXT) and far end cross talk (FEXT) in measurement signals under test provided by a connector having at least 8 signal lines, comprising: compensating for FEXT by use of hardware elements; compensating for NEXT by use of software techniques, wherein said compensating for FEXT by use of hardware elements comprises: providing a first capacitance connected between a first and third of said signal lines; providing a second capacitance connected between a sixth and eighth of said signal lines; providing a third capacitance connected between said third and a fifth of said signal lines; providing a fourth capacitance connected between a fourth and said sixth signal line; providing a first inductance in series between an input and output of said third said signal line; providing a second inductance in series between an input and output of said fifth said signal line; providing a third inductance in series between an input and output of said fourth said signal line; and providing a fourth inductance in series between an input and output of said sixth said signal line.
