35M-4400M Simple Handheld Spectrum Analyzer Tester Measurement Signal Generator with 4.3 inch Screen

Features 1 This product uses the local oscillator signal and the external test signal to obtains the difference frequency signal and calculates the amplitude of the external test signal through the detector 2 Using a high precision VCO source the heterodyne signal frequency can be measured very accurately 3 Since the scanning range is very large 35M 4400M because there is no special detection circuit for the external measurement signal due to cost and other factors the measurement amplitude may have errors 4 The product increases the magnification and displacement parameters and the user can adjust the display waveform by himself The amplitude display is adjusted and calibrated 5 4 3 inch TFTLCD 480x800 color LCD screen widely used for walkie talkie toy remote control 2 4Gwifi Specification 1 Adopt stm32f407 single chip microcomputer main frequency 168M 4 3 inch TFTLCD 480 800 color LCD screen 2 All aluminum alloy shell rotary encoder control 3 USB powered full English display 4 Spectrum display range 35M 4400Mhz input impedance 50 ohms 5 RBW 10khz 50khz 100khz 200khz 500khz a total of 5 gears are adjustable 6 Screen scan points 700 points 7 Scanning span 7M 10Khz 35M 50khz 70M 100Khz 140M 200Khz 350M 500Khz 8 dBm range 80dB 10dB supports manual adjustment of the calibration range There is no amplifier circuit inside the machine If you need to measure small signals you need an external amplifier 9 Maximum acc
