4.3" Color LCD Perfect 35M-4400M Handheld RF Spectrum Analyzer For Walkie Talkie Toy Remote Control Product Description Features:- Using stm32f407 MCU (main frequency 168M) + 4.3-inch TFT (480*800) color LCD screen.- All aluminum alloy shell + rotary encoder control.- Powered via USB, full English display.- Spectrum display range: 35M-4400Mhz; input impedance: 50 ohms.- RBW: 10khz, 50khz, 100khz, 200khz, 500khz, a total of 5 gears are adjustable.- Screen scan points: 700 points.- Scanning span: 7M (10Khz), 35M (50khz), 70M (100Khz), 140M (200Khz), 350M (500Khz).- dBm range: -80dB to 10dB (supports manual adjustment of calibration range). There is no amplifier circuit inside the machine. If you need to measure small signals, you need an external amplifier.- Maximum access signal: 10dB.- Working mode: superheterodyne scanning spectrum analyzer, single scanning time 800ms.- USB power supply is used by default, and customers can add lithium batteries by themselves (Installing lithium batteries instructions is provided. Batteries are not included).- Product specifications: 145mm*70mm*30mm. Weight: 200g.- Use range: walkie-talkie, toy remote control, 2.4G wifi.- It uses local oscillator signal and external test signal to mix to obtain the difference frequency signal, and calculate the external test signal amplitude through a detector. Using a high-precision VCO signal source, the heterodyne signal frequency can be measured very accurately. Since the scanning range is very large (35M-4400M), there is no special detection circuit for external measurement signals due to factors such as cost, and there may be errors in the measurement amplitude. Therefore, the product has added magnification and displacement parameters. Users can adjust the displayed waveform by themselves. The amplitude display can be adjusted and calibrated.Package Included:- 1 x Set of Portable Spectrum AnalyzerNote: Batteries are not included. Detail photoFAQ Q1.
