摘要: A method of measuring the AM/PM conversion of a device under test having a local oscillator is described. A device under test with an embedded local oscillator is provided. A signal source is connected to an input of the device under test. A receiver is connected to an output of the device under test. An input signal is provided by the signal source. The input signal has an initial power level. The input signal is input to the device under test. The power level of the input signal is changed. An output signal of the device under test is measured at different power levels of the input signal.

摘要: A method for measuring group delay on a device under test is described, wherein a test signal with a carrier frequency is generated. An amplitude modulation is applied to said test signal in order to generate at least two group delay signals having frequencies that are symmetrical to the frequency of said test signal. At least said group delay signals are provided to said device under test. Further, a measurement device and a measurement system are described.

A second resistor (32) of the second matching pad (3) is connected to a second resistor (22) of the first matching pad (2), and a third resistor (43) of the third matching pad (4) is connected to a third resistor (23) of the first matching pad (2). A second resistor (42) of the third matching pad (4) can be connected to a device under test (7). A third resistor (33) of the second matching pad (3) can be connected to a calibration standard (5), and a first resistor (31, 41) of the second and the third matching pad (3, 4) are connected in each case to a signal input of an element (11) which suppresses a common-mode component on its two signal inputs.
