Method and test instrument for analyzing a device communicating via a radio link

摘要

The invention related to a method and to a test device for analyzing a device communicating via a radio link. Said device comprises a plurality of antennas for communicating, together comprising an antenna arrangement. The device under test is first disposed in a first position relative to a radio field. A value of at least one piece of channel state information describing a quality of the antenna arrangement obtained via the return channel is determined in said relative position. A change in the relative position of the device under test relative to the radio field is subsequently performed. A second value of the at least on piece of channel state information is determined in said changed, new relative position.

1. A method for analyzing a device communicating via a radio link, which uses an antenna arrangement comprising a plurality of antennas for the communication, with the following method steps:
arranging the device under test in a first relative position relative to a radio field; changing the relative position of the device under test relative to the radio field; characterized in that, in the first position, a first value of at least one channel-status information retransmitted in a return channel is determined and, in the changed relative position, a second value of the at least one channel-status information is determined.
