Abstract:
1. A measurement device configured to be connectable to an analyzer unit, comprising a network analyzer, the measurement device comprising a measuring unit and a calibration and control unit connected to and integral with said measuring unit, said calibration and control unit being configured to enable connection of the measuring unit to the analyzer unit, said calibration and control unit comprising: at least three calibration load terminals of certain RF reflection coefficients; a memory utility storing recorded data provided in a first calibration procedure carried out off-line before integrating the calibration and control unit with the measuring unit, said recorded data being indicative of measured RF reflection coefficients of said at least three calibration load terminals and indicative of measured RF transfer coefficients of the calibration and control unit, at least one switch comprising first and second connection ports for connecting to the measurement unit and to the network analyzer respectively, and at least three connection ports for connecting to said at least three calibration load terminals respectively, the switch having at least four switching states associated with respectively said at least three calibration load terminals and said measurement unit, thereby enabling selective connection of each one of said calibration load terminals and said measurement unit to the network analyzer, enabling calculation of the RF response of the measuring unit while the measurement unit remains integral with the calibration and control unit, and a controller utility programmed for controlling operation of the memory utility and said at least one switch for recording the measured data indicative of said RF reflection coefficients of said at least three calibration load terminals and RF transfer coefficients of the calibration and control unit data to be further used for a calibration process for the measurement unit while the measurement unit remains integral with the calibration and control unit.
