35M-4400MHz Spectrum Analyzer Signal Source Tracking Source Touch Screen Control

Specifications: 1. The stm32f407 single chip microcomputer (main frequency 168M)+4.3 inch TFTLCD (480 * 800) color LCD screen is adopted. 2. All aluminum alloy shell+rotary encoder control. 3. USB power supply, full English display. 4. Spectrum display range: 35M-4400Mhz; Input impedance: 50 ohms. 5. RBW: 5 gears (10khz, 50khz, 100khz, 200khz, 500khz) are adjustable. 6. Screen scanning points: 700 points. 7. Scanning span: 7M (10Khz), 35M (50khz), 70M (100Khz), 140M (200Khz), 350M (500Khz). 8. DBm range: - 80dB ------ 10dB (manual adjustment of calibration amplitude is supported). The machine does not have an circuit inside. If small signals need to be measured, an external is required. 9. Maximum access signal: 10dB. 10. Working mode: superheterodyne scanning spectrometer, single scanning time 800ms. 11. The internal lithium battery charging circuit is integrated. Due to logistics safety reasons, this product is shipped without batteries. By default, USB is used for power supply. Customers can add lithium batteries (provide instructions for installing lithium batteries). 12. Product specification: 145mm * 70mm * 30mm. Weight: 200g. 13. Scope of use: walkie talkie, toy remote control, 2.4Gwifi.

Other instructions: This product uses local oscillator signal and external measurement signal to obtain differential frequency signal, and calculates the amplitude of external measurement signal through the detector. Using high precision VCO signal source, heterodyne signal frequency can be measured very accurately. Because the scanning range is very large (35M-4400M), and because there is no special detection circuit for the external measured signal due to cost and other factors, there may be errors in the measurement amplitude, so the product has added two parameters, magnification and displacement. The user can adjust the display waveform by himself to adjust and calibrate the amplitude display
