Disclosed are systems, devices and methods related to scanners that can be utilized for multiple electrical and/or magnetic field measurements at different locations of a radio-frequency (RF) module. In some embodiments, a scanning system can include a miniature probe such as a magnetic probe, a fixture system configured to hold a device under test (DUT) such as an RF module, an operating system configured to operate the DUT, and a measurement system configured to obtain field strength measurements through the miniature probe at different locations of the DUT. Such measurements can yield a near-field distribution over a plurality of selected areas of the DUT, with each of the selected areas being smaller than an overall lateral area of the DUT. In some implementations, such a scanning system can be utilized to facilitate applications such as electromagnetic (EM) shielding designs. |
