4.3 inch LCD Display Handheld Spectrum Analyzer Signal Generator 35MHz-4.4GHz. The main chip STM32F407 (clocked at 168M). 4.3 inch TFTLCD (480 800) display. All aluminum alloy shell + rotary encoder control.Build in 4000mAh battery, English interface. Spectrum display range: 35M-4400Mhz; input impedance: 50 ohms. RBW: 5 gears adjustable 10khz, 50khz, 100khz, 200khz, 500khz. Screen scanning points: 700 points.
Scanning span: 7M (10Khz), 35M (50khz), 70M (100Khz), 140M (200Khz), 350M (500Khz). DBm range: -80dB ----- 10dB (supports manual adjustment of the calibration range). There is no amplifier circuit inside. If you need to measure small signals, you need an external amplifier.
Working mode: Super heterodyne scanning spectrum analyzer, single scanning time 800ms. Product specifications: 145mm 70mm 30mm.
Scope of application: walkie-talkie, toy remote control, 2.4Gwifi. Mix the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculate the external test signal amplitude through the detector.Using a high-precision VCO signal source, the heterodyne signal frequency can be measured very accurately. Because the scanning range is very large (35M-4400M), due to cost reasons, there is no dedicated detection circuit for the external test signal. There may be errors in the measurement amplitude. Therefore, the product has increased the magnification and displacement parameters. The display is adjusted and calibrated. We believe our items are so outstanding. All products are quality checked.
