摘要： Probe for testing a radio frequency device, test system and test method. A probe is used for measuring radio frequency signals provided by the device under test or for providing test signals to the device under test. In particular, the probe comprises a power detector directly connected to the contacting elements of the probe. Accordingly, such a power detector can provide a power signal highly correlated with the power signal of a radio frequency signal at input or output terminals connected to the probe.

摘要： An over the aft measurement module comprises an antenna, adapted to receive a first measuring signal from a device under test or adapted to transmit a second measuring signal to the device under test. Furthermore, the over the air measurement module comprises a mixer, directly connected to said antenna, adapted to reduce or increase a frequency of the received first measuring signal, resulting in a frequency reduced or increased first measuring signal, or adapted to increase or reduce a frequency of a frequency reduced or increased second measuring signal, resulting in the second measuring signal. In addition to this, the over the air measurement module comprises a first connector, connected to said mixer, adapted to input a local oscillator signal into the mixer for frequency conversion.
