Abstract
A method for testing radio frequency interference (RFI) of electromagnetic compatibility (EMC) chamber includes: setting a threshold value of noise bandwidth (NBW) on the computer in response to user's operation, activating a signal source in the EMC chamber to transmit test signals using the computer, adjusting the antenna to a predetermined height and orients a polarization direction along a vertical direction, and controlling the signal source to rotate using the computer, testing the EMC chamber to obtain a NBW value, and comparing the NBW value with the threshold value to determine the RFI of the EMC chamber.
Claims8
A method for testing radio frequency interference (RFI) of an electromagnetic compatibility (EMC) chamber, wherein the EMC chamber comprises at least one antenna for communicating with a computer in an operating room, the method comprising:
- (1) setting a threshold value of noise bandwidth (NBW) on the computer in response to user's operation;
- (2) activating a signal source in the EMC chamber to transmit test signals using the computer;
- (3) adjusting the at least one antenna to a predetermined height, and orienting a polarization direction of the at least one antenna along a vertical direction, and controlling the signal source to rotate using the computer;
- (4) testing the EMC chamber to obtain a first NBW value thereof and storing the first NBW value in the computer;
- and
- (5) comparing the first NBW value with the threshold value to determine the RFI of the EMC chamber using the computer.
