Embodiment Construction

[0043] Next, the technical solutions in the embodiments of the present invention will be described in the following examples, and the described embodiments are merely, not all of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained without creative labor are not made in the premise of creative labor.

[0044] It should be noted that all directional instructions (such as above, lower, left, right, front, and post, ...) are only used in a particular attitude (as shown in the accompanying drawings). The relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication is also changed accordingly.

[0045] In the present invention, the term "connection", "fixed", etc. It is a mechanical connection or an electrical connection; it can be directly connected, or the intermediate medium can be indirectly connected, which may be in connection with the interior of the...

Abstract

The invention discloses an electromagnetic reflection signal measuring device, method and system, and belongs to the field of electromagnetic signal measurement. The electromagnetic reflection signal measuring device comprises a machine base, a circuit board supporting piece, a distance and angle adjusting assembly and a signal reflection piece. Wherein the circuit board supporting piece is arranged on the machine base, one end of the distance and angle adjusting assembly is connected with the machine base, the other end of the distance and angle adjusting assembly is connected with the signal reflecting piece, the angle and the position of the signal emitting piece and the distance between the signal emitting piece and a circuit board to be detected can be adjusted, and the signal reflecting piece forms a simulation shell in an enclosing mode and accommodates the circuit board supporting piece. During measurement, the relative position relation between the signal reflection piece and the circuit board to be detected is adjusted, so that the influence area of the electromagnetic reflection signal on the circuit board to be detected is changed; by measuring the affected state of the working circuit on the circuit board to be detected, the angle and position of the signal reflecting piece and the relation between the distance between the signal reflecting piece and the circuit board to be detected and the electromagnetic reflection signal are obtained.

Description

Technical field [0001] The present invention relates to a field of electromagnetic signal measurement, and more particularly to an electromagnetic reflection signal measuring device, method, and system. Background technique [0002] With the popularity of radio frequency circuits and high-speed digital circuits, consumer electronics use iron shells, double weights, or shielding, more and more, with high frequency technology development and chip minimal makeup process, related The circuit is also more and more sensitive. [0003] Due to the particularity of the RF circuit and the high-speed digital circuit, the high-speed signal will generate reflective electromagnetic waves via a nearby metal plate. If the reflected wave is just a sensitive circuit, it will affect the work of normal circuitry. When designing the circuit, it is necessary to prevent the reflected electromagnetic wave affecting the sensitive circuit, so systematic measurement is required to be influentially affected...
