Patent ID: 11892486
Assignee: BOE TECHNOLOGY GROUP CO., LTD.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 4:
5. A frequency debugging system, comprising:
an electronic device including an antenna to be tested and a capacitor to be tested;
a test coil configured to receive a signal sent by the antenna to be tested;
a frequency tester connected to the test coil and configured to detect a frequency of the signal in the test coil from the antenna to be tested, the frequency of the signal being an operating frequency of the electronic device;
a terminal connected to the frequency tester, the terminal being configured to receive the operating frequency of the electronic device sent by the frequency tester, and to determine whether a deviation of the operating frequency of the electronic device from a target frequency is within an allowable range; and
the frequency debugging board according to claim 1, wherein the frequency debugging board is connected to the terminal, and is arranged opposite to a side, where the antenna to be tested and the capacitor to be tested are located, of the electronic device; the frequency debugging board is configured to: receive an instruction sent by the terminal, and change at least one of a capacitance of the variable capacitor and a state of the at least one switch according to the instruction, so as to adjust the operating frequency of the electronic device to keep the deviation of the operating frequency of the electronic device from the target frequency within the allowable range.
