A signal processing circuit for a measurement instrument is described. The signal processing circuit comprises a measurement input, a first measurement channel, a second measurement channel, and a noise canceling circuit. The first measurement channel comprises a first wideband analog-to-digital converter (ADC) and a first transformation circuit. An output signal of the first measurement channel is a first frequency domain signal. An output signal of the second measurement channel is a second frequency domain signal. The first frequency domain signal and the second frequency domain signal are a complex-valued signal, respectively. The noise canceling circuit is configured to receive the first frequency domain signal and the second frequency domain signal and to determine a combined average of the first frequency domain signal and of the second frequency domain signal over a predetermined number of frequency bins, thereby obtaining a complex-valued average signal. Further, a measurement system is described.

Signal processing circuit and measurement system

The invention relates to a measurement system, including a signal analyzer or monitoring receiver, for measuring and analyzing modulated signals. The system includes a signal acquisition device having input port(s), wherein the signal acquisition device is configured to capture modulated signal(s) applied to the input ports, wherein each captured modulated signal can be represented as an I/Q signal; wherein the signal acquisition device generates at least two digital I/Q data streams based on the one or more modulated signals, wherein the at least two digital I/Q data streams are generated in parallel. The measurement system includes a selection device to select at least one target frequency bandwidth in each of the at least two digital I/Q data streams; and a signal processing device configured to analyze the at least two digital I/Q data streams in the selected target frequency bandwidths.

Measurement system and method for measuring and analyzing modulated signals

Embodiments of the present disclosure relate to methods of finding optimized analog measurement hardware settings of a measurement system for a target measurement. The method can include one or more of the following steps: applying initial settings to the measurement system; varying the settings over a power sweep while processing a test signal used for the target measurement or a representative signal; performing the target measurement during the power sweep, thereby determining a hardware contribution of the measurement system over the power sweep; and identifying the respective settings that lead to a minimum hardware contribution of the measurement system at various powers.

Method of finding optimized analog measurement hardware settings as well as method of measuring a device under test

A setting of a measurement instrument comprises the providing a reference measurement instrument that uses at least one instrument parameter. A training phase is performed for a particular signal type to be processed by said reference measurement instrument in order to retrieve an optimal setting for said at least one instrument parameter. A lookup table is created for said particular signal type, said lookup table comprising at least said optimal setting for said at least one instrument parameter.

Method of setting a measurement instrument and system for setting a measurement instrument

A method for analyzing the resolution and/or the accuracy of a transmission unit of a radar sensor is described wherein a transmitter signal is received via a receiving unit. At least one echo signal based on said received signal is simulated. The frequency difference of said transmitter signal and said echo signal is determined. Said frequency difference is filtered and transformed in order to obtain a transform. At least one maximum of said frequency difference in said transform is detected. Spectral properties of said frequency difference in said transform are determined. At least one quality parameter of said spectral properties is outputted. Further, a radar sensor is described.
