The wireless microphone interference detector is mainly used to detect the frequency state of the wireless microphone signal from 350MHz to 950mhz,  but it also has some other excellent functions. The 3.2-inch full-color touch screen of the detector has a folding antenna, which is used to receive the U-section wireless microphone input from 350MHz to 950mhz. The band-pass filter with switchable resolution is applicable to the two ranges of 2.6khz to 640kHz. The color display screen displays 290 scanning points, The input step attenuator covers the whole frequency range. When it is not used as an interference detector from 0dB to 31dB, it can be used as an input field strength meter for checking the antenna amplifier system, and observe the signal strength to judge the fault of the antenna amplifier. It can be used as a signal generator. The UHF square wave output is between 350MHz and 950mhz. The built-in calibration signal generator is used for automatic self inspection of the rechargeable battery. It can be used continuously for at least 4 hours with low cost and very small external dimensions
