摘要： A device for determining an estimated value for a mean power of the noise-signal sequence, which is superposed on an undisturbed periodic transmitted-signal sequence, determines a mean power of a received-signal sequence, which corresponds to the undisturbed periodic transmitted-signal sequence with the addition of the superposed noise-signal sequence. It then estimates an estimated-signal sequence for the undisturbed periodic transmitted-signal sequence from the received-signal sequence. Following this, a mean power of the estimated-signal sequence and the estimated value of the mean power of the noise-signal sequence is determined from a difference between the determined mean power of the received-signal sequence and the determined mean power of the estimated-signal sequence.

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.

摘要： A measuring device comprises at least one port, an external cable connected to the at least one port, a transmitter connected to the at least one port through a switch, a receiver connected to the at least one port through the switch and a reference path connecting the transmitter with the receiver through the switch. The cable is connected to calibration elements, e.g., short and open. The switch alternately switch in a manner that in a first state the transmitter and the receiver are connected to the at least one port and that in a second state the transmitter and the receiver are connected via the reference path.
