Abstract
Abstract A data processing system includes a keyboard having a -number of keys for entering numeric values and a number of terminator keys for terminating an entered value with the proper exponent, including the proper parameter units, to indicate the weight to be given the entered value. The data processing system is incorporated in an RF vector network analyzer for laboratory and automated production measurements. The data processing system provides for fully coordinated communications between subsystem modules; real time, two channel, precision vector measurements with complete, internal error correction; trace math with stored data; and split screen and combined time and frequency domain analysis and display.
