Abstract
A passive, highly efficient, low noise adapter device includes a balun and noise reduction circuitry uniquely configured to converting an unbalanced signal line on a 50 ohm signal line to a balanced signal on a 100 ohm transmission line or vice versa. The device facilitates the use of commercially available and accepted test equipment for accurate transmission measurements on balanced twisted pairs of cables and connectors. A typical utilization includes an adapter device connected between the 100 ohm twisted pair cable and suitable test equipment such as a network analyzer and/or a signal generator for determining losses in the telephone wire and connectors.
