Description

Detection device of radio frequency equipment

Technical Field

The utility model relates to the technical field of detection, in particular to a detection device of radio frequency equipment.

Background

As wireless technology expands toward the millimeter wave band, the way in which radio frequency performance of wireless devices is measured evolves from conductive measurements to radiometric measurements. The radiation test environment for radio frequency performance of the wireless equipment consists of an object to be tested, an electromagnetic propagation space, an antenna, a conduction path and a test instrument. When the radio frequency performance test is executed, signals emitted by the EUT (object under test) are received by the antenna through the electromagnetic propagation space and then fed into the rear-end test instrument through the conduction path.

In the prior art, prior to performing radio frequency performance tests, the radiation measurement path needs to be calibrated in advance. As shown in fig. 1, when performing radiation path calibration, a reference signal needs to be generated by a signal source via a transmission path (including some radio frequency devices used for calibration) and a transmission antenna, and the reference signal is received by a radiation test system after passing through a radiation test path. As shown in fig. 2, the signals received by the radiation testing system are fed into the receiver via the receive antenna and receive path therein (including some of the radio frequency devices used for testing). The calibration results are used to correct the test system. In performing the radio frequency performance test, the signals transmitted by the EUT are fed to the rear-end test instrument via a conductive path after being received by the receiving antenna through the electromagnetic propagation space. As shown in fig. 3, the EUT is placed on a positioner that rotates the EUT through horizontal and vertical angles to measure the maximum radiation level at each angle of the EUT. After performing the radiation path calibration, the transmit antenna, transmit path and signal source of the calibration system are removed and replaced with EUT and positioner of the test system to perform the radio frequency performance test. In the replacement, the alignment of the EUT center point of the test system and the transmitting antenna center point of the calibration system needs to be ensured.

At present, the test system and the calibration system are two independent systems, and are not designed in an associated mode, so that during replacement, the EUT center point of the test system cannot be accurately aligned with the transmitting antenna center point of the calibration system, the calibration result cannot be corrected correctly, and the accuracy of the test result cannot be guaranteed. Especially for millimeter wave frequency band application, because the frequency is higher, the wavelength is shorter, the antenna wave beam is narrower, and the requirement on alignment of the antenna radiation pattern is higher, even fine alignment deviation can generate extremely large test errors.

Therefore, a detecting device for a radio frequency device is needed to solve the above-mentioned problems.
