Embodiment Construction

[0036] For adjusting the potentiometer, change the potentiometer to a digital potentiometer (except for the field strength signal processing unit). The potentiometer part of the digital potentiometer is connected to the original potentiometer position, and the control part of the digital potentiometer is connected to the microcontroller. The digital potentiometer is controlled by the microcontroller, and the tap position of the potentiometer is changed to change the output signal amplitude of the potentiometer, or to change the input resistance and feedback resistance of the amplifier to achieve amplifier gain adjustment.

[0037] For adjusting the trimmer capacitor, the trimmer capacitor is changed to a varactor diode, and the pulse level with variable duty ratio output by the microcontroller is controlled by a smooth voltage signal through a passive low-pass filter. Changing the pulse duty cycle also changes the varactor junction capacitance. It can also be a digital potent...

Abstract

The invention relates to an automatic debugging system for testing a wireless microphone, which comprises a transmitter test fixture, a receiver test fixture, a testing computer, testing computer software and instrument equipment which can be connected to the computer for realizing control on the basis of the computer software. The invention also relates to a method for automatically debugging the wireless microphone through the debugging system. By the debugging system and the debugging method, the complete automatic debugging in the process of producing the wireless microphone is realized.

Description

technical field [0001] The invention relates to a wireless microphone, and further relates to a method for realizing automatic debugging during production of the wireless microphone and an automatic debugging system thereof. Background technique [0002] A wireless microphone, or a wireless microphone, is an audio equipment that transmits sound signals. It consists of a transmitter and a receiver. It is usually called a wireless microphone system. It is essentially a one-way wireless communication system. The early wireless microphones were realized by FM frequency modulation, and later a quartz oscillator was used to generate accurate and stable fixed frequencies for transmission and reception. This kind of microphone and receiver only fixed a single frequency paired for use. Now professional wireless microphones are all using frequency synthesis (PLL Synthesized), which can switch the desired working channel arbitrarily within the preset bandwidth, so as to avoid environm...
