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 measurement device for measuring the impedance of a device under test is described. Said measurement device comprises at least one signal generator for generating a signal with a certain frequency wherein said signal is used for testing said device under test. Said measurement device further has at least one shunt resistor that is used for determining the electric current of said signal. Said device also comprise at least two voltage channels for measuring the voltage across said device under test. Said measurement device is an oscilloscope having at least four voltage inputs and wherein said measurement device is configured to derive the impedance of said device from said electric current and said voltage. Further, a method for measuring the impedance of a device under test is described.
