Abstract
Embodiments are disclosed of a switchplexer for performing test operations on a radio device. The switchplexer comprises a plurality of test ports corresponding to a plurality of radio device ports and a plurality of switches for routing test signals between the individual test ports. Processing logic is disclosed for controlling actuation of the switches to route test signals between individual test ports. The switchplexer disclosed herein may be incorporated into a mobile test device for self-test operations or may be used in a manufacturing or maintenance facility for testing and calibration operations.
Claims20
A switchplexer for performing test operations on a radio device, comprising:
- a plurality of test ports corresponding to a plurality of radio device ports;
- a plurality of switches comprising at least a transmitter switch and a receiver switch, the transmitter switch configured to allow testing via a transmitter path and the receiver switch configured to allow testing via a receiver path;
- a circuit operable to provide a test signal measurement value corresponding to the presence of a test signal at individual test ports of said plurality of test ports;
- and
- processing logic operable to actuate said plurality of switches to route said test signal between said individual test ports;
- wherein said test signal measurement values are used to perform self-test operations associated with at least a transmitter or a receiver of said radio device via the transmitter path or the receiver path, respectively.
A computer-implemented method of using a switchplexer to perform test operations on a radio device, comprising:
- providing a plurality of test ports corresponding to a plurality of radio device ports;
- providing a plurality of switches comprising at a least one transmitter switch and at least one receiver switch;
- generating a test signal measurement value corresponding to the presence of a test signal at individual test ports of said plurality of test ports;
- and
- using processing logic to actuate said plurality of switches to route said test signal between said individual test ports;
- wherein said test signal measurement values are used to perform self-test operations associated with a transmitter and/or a receiver of said radio device.
A switchplexer for performing calibration operations on a radio device, comprising:
- a plurality of test ports corresponding to a plurality of radio device ports, the plurality of test ports comprising at least a transmitter test port and a receiver test port;
- a plurality of switches comprising at least a transmitter switch and a receiver switch, the transmitter switch configured to allow testing via a transmitter path and the receiver switch configured to allow testing via a receiver path;
- a circuit operable to provide a test signal measurement value corresponding to the presence of a test signal at individual test ports of said plurality of test ports;
- and
- processing logic operable to actuate said plurality of switches to route said test signal between said individual test ports;
- wherein said test signal measurement values are used to perform calibration operations associated with a transmitter and/or a receiver of said radio device.
