Abstract
A method and system for measuring a device under test are disclosed. In some embodiments, a method of implementing a measurement system is provided. The method includes providing a plurality of nodes, each node including a combination of a communication tester configured to generate a communication signal and a channel emulator configured to emulate a channel, and providing a user interface configured to enable a user to control at least one of the plurality of nodes.
Claims18
A method of implementing a measurement system to operate in an outgoing mode, the method comprising:
- providing a plurality of nodes, each node including a combination of an antenna, a communication tester configured to generate a communication signal and a channel emulator configured to emulate a channel, the plurality of nodes being distributed about a test volume surrounding a device under test, DUT, each node positioned to cause propagation in a different direction, the emulator of each of a plurality of nodes emulating impairment in the different direction of propagation;
- and
- providing a user interface configured to enable a user to control at least one of the plurality of nodes.
A method of implementing a measurement system to operate in an incoming mode, the method comprising:
- providing a plurality of nodes, each node having a combination of an antenna, a channel emulator configured to receive and impair a communication signal from a device under test, DUT, and a communication tester configured to receive the impaired communication signal, the plurality of nodes being distributed about a test volume surrounding the DUT, each node positioned to receive propagation from a different direction, the emulator of each of a plurality of nodes emulating impairment in the different direction of propagation;
- and
- providing a user interface configured to enable a user to control at least one of the plurality of nodes.
A measurement system operable in an outgoing mode and an incoming node, comprising:
- for each of a plurality of positions within a test chamber, a bi-directional test node, each node comprising:
- an antenna:
- a communication tester configured to generate a transmit signal and to receive an impaired receive signal;
- and
- a channel emulator configured to:
- impair the transmit signal, the impaired transmit signal to be transmitted by an antenna to which the communication tester corresponds;
- and
- impair the receive signal to produce the impaired receive signal, the receive signal being received from the antenna to which the communication tester corresponds;
- each node positioned to cause propagation in a different direction, the channel emulator of each of a plurality of nodes emulating impairment in the different direction of propagation.
