    摘要: A measuring device for measuring a power of a measurement signal comprises an analog-processing unit (1) and a calibration unit (5) for the implementation of a calibration procedure. The analog-processing unit (1) provides two detector diodes (14, 15) connected in an antiparallel manner relative to a signal input (10) and an amplifier (50) for the amplification of signals which are derived from output signals of the detector diodes (14, 15). The analog-processing unit (1) further provides a chopper unit (28) which is connected at two terminals in series between the detector diodes (14, 15) and the amplifier (50). In this context, the calibration unit (5) comprises at least one current source, wherein the current sources (46, 47) is connected to at least one input terminal of the amplifier (50).

    摘要: A frequency-converting sensor is provided for generating at least a radio frequency signal parameter, such as an electrical power value. The sensor comprises an analog receiving section configured to convert an input signal into corresponding I/Q components using a local oscillator frequency, an analog to digital converting unit configured to convert the corresponding analog I/Q values into digital I/Q values, and a digital processing unit. The digital processing unit comprises an adjustable filtering unit configured to select a sideband of the digital I/Q values, and a calculating unit configured to calculate the radio frequency signal parameter from the I/Q-values of the selected sideband. A system is further provided for analyzing radio frequency input signal parameters, wherein the system incorporates a device under test, which generates the radio frequency signal, the sensor and a display device.
