Abstract
In an apparatus and method for measuring noise power of each antenna in a multiple input multiple output (MIMO) antenna system, the apparatus includes a shielding box for the MIMO antenna system, shielding against electromagnetic interference, and a network analyzer (NA). The NA further includes numbers of test module, control module, and display module. The NA obtains each calibration parameter, each port noise power, and each measured S parameter, and obtains actual S parameter of each measured quantity according to a first equation, and thus obtains assessment of the MIMO antenna system. The MIMO antenna system noise power measuring method and apparatus of the disclosure take advantage of multiple ports of the NA, and set reference planes in the shielding box and import measuring method to the NA to obtain precise MIMO antenna system noise power. The apparatus can measure each antenna of MIMO antenna system simultaneously and synchronously.
