The present disclosure provides a main measurement device for simultaneously measuring signals with at least one secondary measurement device, the main measurement device comprising a reference signal output port configured to couple to the at least one secondary measurement device, a reference signal generator coupled to the reference signal output port and configured to generate a reference signal, a measurement port configured to receive a signal to be measured, a trigger output port configured to couple to a trigger input port of the at least one secondary measurement device and to output a trigger signal, and a controllably switchable internal signal path configured to selectively couple the reference signal generator with the measurement port. Further, the present invention discloses a respective secondary measurement device, a respective measurement system, and a respective method.

Main measurement device, secondary measurement device, measurement system and method

A power analyzer system for correlating power consumption and RF signals of a device under test has a RF sensor unit, a power probe unit and an analysis device being a physically separate device from the RF sensor unit and the power probe unit. The analysis device has a standardized interface module by which the analysis device is connected to the RF sensor unit and the power probe unit. The analysis device is configured to control the RF sensor unit and the power probe unit and to synchronously display a representation of the RF signal of the device under test and a representation of the power consumption of the device under test. Further, a power analyzer setup is shown. The units or devices can comprise one or more circuits to carry out its respective or other functionality.

Power analyzer system as well as power analyzer setup

A Multi-Domain Measurement System has an oscilloscope unit and a power probe unit. The oscilloscope unit comprises an analog input channel for receiving a measured analog signal and a first digital interface for receiving digitized measurement values from said power probe unit. The power probe unit is connected to the first digital interface for providing digitized measurements of a power supply signal. The power probe unit and the analog input channel are assigned to a device under test for simultaneously measuring signals in different domains. The power probe unit has a power probe measurement channel providing a vertical digitizing resolution that is at least two times higher than a vertical digitizing resolution of the analog input channel. Further, uses of a Multi-Domain Measurement System are provided.
