Determining ambient noise in a device under test electromagnetic compatibility test environment
First Claim
1. A method, comprising:
- determining, by a system comprising a processor via a radio frequency input port of the system, an ambient electromagnetic noise corresponding to the system;
in response to the determining the ambient electromagnetic noise, determining, by the system, via the radio frequency input port, a radio frequency signature of a device under test;
generating, by the system, request data, representative of a request that an antenna be connected to the radio frequency input port, to be displayed by a user interface of the system; and
subtracting, by the system, the ambient electromagnetic noise from the radio frequency signature to obtain a normalized value representative of an electromagnetic emission of the device under test.

Abstract
Determining ambient noise in a device under test electromagnetic compatibility test environment is presented herein. A method can include determining, by a system comprising a processor via a radio frequency input port of the system, an ambient electromagnetic noise corresponding to the system; and in response to determining, by the system via the radio frequency input port, a radio frequency signature of a device under test, subtracting, by the system, the ambient electromagnetic noise from the radio frequency signature to obtain a normalized value representing an electromagnetic emission of the device under test. In an example, an antenna/coaxial cable has been connected to the radio frequency input port, the ambient electromagnetic noise can be determined using the antenna/coaxial cable, and a radiated/conducted electromagnetic characteristic of the device under test representing the radio frequency signature of the device under test can be determined using the antenna/coaxial cable.
