Measurement system and method for operating a measurement system

A test setup for power measurement of a fast switching active antenna array with a beam switching time lower than one microsecond is described. The test setup includes at least two detector modules for detecting a signal transmitted by the fast switching active antenna array and a power sensor module for measuring the power of at least one signal received. The power sensor module has an analog-to-digital converter circuit for converting an analog signal into a digital signal. Each of the detector modules includes at least one antenna via which at least one signal transmitted by the fast switching active antenna array is received. The at least two detector modules are positioned in at least two predefined main radiation directions of the fast switching active antenna array. Each of the detector modules has a rise time, the rise time being lower than the beam switching time of the fast switching active antenna array.

Power measurement apparatus

A measuring system contains a signal generator and at least one power meter. A device under test is supplied with a signal from the signal generator. A signal output by the device under test can be measured by the first power meter. In this context, the signal generator and the power meter are connected by a bidirectional communications link.

Power measurement with a signal generator

In a system for measuring at least one high-frequency signal, comprising at least one broadband probe and at least one measuring apparatus, each broadband probe and each measuring apparatus comprise a high-frequency connection for transmitting a high-frequency signal, and each measuring apparatus, or instead of a measuring apparatus each signal processing unit, comprises power supply connections for supplying power to each of the broadband probes, and comprise data signal connections for transmitting communication data between the measuring apparatus or signal processing unit and the broadband probe head. The power supply and data signal connections of each measuring apparatus, each signal processing unit, and each broadband probe are each identical with respect to the signal assignment and signal specification and are designed in accordance with an interface standard, and in each measuring apparatus, each signal processing unit and either directly in the broadband probe or in an adapter unit electrically connected to the broadband probe head are each guided in an identically standardized jack.

System for measuring high-frequency signals with standardized power-supply and data interface

A measuring device for measuring the power of a high-frequency signal including a detector for detecting the high-frequency signal and for generating an analog detector signal, an analog/digital converter for generating a digital signal and an evaluation device for evaluating the digital signal. A dither supply device for the supply of a dither signal and a chopper, which periodically chops the analog detector signal with a chopper signal, are disposed between the detector and the analog/digital converter. In this context, the dither signal is supplied synchronously to the chopper signal.
