DEFINITION
Classification: 455/226.1
Measuring or testing of receiver:
(under subclass 130) Subject matter comprising means which, in use, determines qualitatively or quantitatively, a receiver characteristic.
(1) Note. The receiver may not be operative as to communication during test, and the receiver is usually a block and claimed at least nominally.

331, Oscillators, appropriate subclasses for specific elements (e.g., noise generator), with no more than means for coupling to a receiver.
343, Communications: Radio Wave Antennas,
703, for measuring of a signal with an antenna and a nominal receiver or with quantitative means.
