The radio frequency (RF) probe socket is disclosed. The probe socket includes a conductive noise shielding body configured to accommodate the plurality of signal probes to be parallel with one another while exposing opposite ends thereof, and shield noise; upper and lower noise shielding walls configured to be extended from the noise shielding body to some areas between the exposed opposite ends of the plurality of signal probes; and upper and lower holding members configured to be arranged on top and bottom sides of the noise shielding body, support the exposed opposite ends of the plurality of signal probes, and comprise accommodating grooves accommodate the noise shielding walls, respectively. With this, the noise shielding wall extended from the shielding block makes a shield between the signal probe pins passing through the upper and lower holding member, thereby preventing crosstalk between the signal probe pins.

Embodiments provided describe detections of RF leakage test signal emanating from cable plant. In one embodiment a single mobile receive antenna, connected to a complex demodulator mobile receiver, receives a stabilized test signal radiating from the cable plant. The test signal may be a known continuous wave (CW) carrier or other deterministic signal. The received test signal varies in phase as a function of a position of the mobile receive antenna relative to the location of a leakage antenna. The phase variance forms a Doppler shift as the test antenna moves relative to the leakage antenna. The receiver generates multiple in-phase (I) and quadrature (Q) test signal samples over a SPA (synthetic phased array) distance as the test antenna's travels, and the samples are inserted into a Fourier transform. The result of the transform is instantaneous Doppler frequency shift, from which a bearing angle can be computed.

An electronic device may include a shaft insertable into a target area, and an electronic component configured to generate a signal. The electronic component may be on or within the shaft. The electronic device may also include at least one antenna on or within the shaft. The electronic device may also include a receiver operatively coupled to the antenna. The receiver may monitor an electrical characteristic of the antenna to identify an effect of an electromagnetic field on the electrical characteristic of the antenna. The electronic device may also include a processor communicatively coupled to the receiver. At least one of the receiver and the processor may predict an effect of the electromagnetic field on the signal generated by the electronic component, based at least in part on the effect of the electromagnetic field on the electrical characteristic of the antenna.

A system to test efficacy of electromagnetic shielding includes a radio frequency anechoic housing and a testing device. The testing device includes a signal source, at least one antenna, and a receiver. When one of the antenna is connected to the signal source, the receiver receives a first frequency field. When the antenna and the signal source are in the shielding shell and the shielding shell is in the radio frequency anechoic housing, the receiver receives a second frequency field. Values of the shielding efficacy are obtained according to the first frequency field and the second frequency field. A determination of whether the shielding shell meets requirements is obtained according to the values of the shielding efficacy. A method for testing shielding efficacy is also disclosed.

Embodiments of the present disclosure relate to a method of testing a radio frequency (RF) attenuation of a radar cover. A radiation detector is provided. The radiation detector is located with respect to a radar device and/or a radar cover at a distance. A reference value of radiated power is obtained. A radar signal radiated by the radar device is received by the radiation detector. A radiated power is determined based on the radar signal received.

A method is provided that includes setting up a composite material structure under test (SUT) between a transmit coil and a receive coil. The transmit coil is driven with a RF signal over a plurality of frequencies, thereby causing the transmit coil to produce a magnetic field that by magnetic coupling through the SUT induces a voltage in the receive coil. The voltage in the receive coil is measured, and from the voltage, a measurement of attenuation of the RF signal caused by the SUT between the transmit coil and receive coil is produced. And an effective conductivity of the SUT is calculated from the measurement of attenuation.
