摘要： A mobile radio testing device (10) for protocol testing of a device under test (20) is provided. The mobile radio testing device (10) comprises a downlink path (11) and an uplink path (13), wherein the uplink path (13) comprises at least a first analysis mode (15) and a second analysis mode (17). In this context, the mobile radio testing device (10) includes a demodulation processing unit (12) for analyzing signals from the device under test (20) in the first analysis mode (15). In addition, the second analysis mode (17) analyzes signals from the device under test (20) without using the demodulation processing unit (12) .

摘要： A coupler (100), in particular a resistive coupler, wherein all ports (102, 107, 108) are at least partially or completely arranged in or at a connector (110). The coupler (100) comprises resistors (103, 104, 105, 106) which are adapted to sum and/or divide the incoming and/or outgoing signal. The resistors (103, 104, 105, 106) are arranged at or in the connector (110). A sum port (107) and/or at least two dividing ports (102, 108) are arranged on a substrate (101).
