35M-4400MHZ Handheld Spectrum Analyzer Signal Generator 4.3 Inch Screen Spectrum Analyzer

 introduce:
This product uses the local oscillator signal and the external test signal to obtain the difference frequency signal, and calculates the amplitude of the external test signal through the detector. Using a high precision VCO source, the heterodyne signal frequency can be measured very accurately. Due to the large scanning range (35M-4400M), due to factors such as cost, there is no special detection circuit for external measurement signals, so there may be errors in the measurement range. Therefore, the product has added magnification and displacement parameters, and users can adjust the displayed waveform by themselves. Adjust and calibrate the amplitude display.

feature:
1. Adopt stm32f407 single-chip microcomputer (main frequency 168M) + 4.3-inch TFTLCD (480*800) color LCD screen.
2. All aluminum alloy casing + rotary encoder control.
3. USB power supply, 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 scanning 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.
