Introduction:
1. Using stm32f407 single-chip microcomputer (main frequency 168M) + 4.3-inch TFT (480*800) color LCD screen.
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: 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 to 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 access signal: 10dB.
10. Working mode: superheterodyne scanning spectrum analyzer, single scanning time 800ms.
11. The internal integrated lithium battery charging circuit, due to logistics safety reasons, this product is shipped without batteries. By default, usb is used for power supply, and customers can add lithium batteries by themselves (provide instructions for installing lithium batteries).
12. Product specifications: 145mm*70mm*30mm. Product Weight: 200g.
13. Use range: walkie-talkie, toy remote control, 2.4Gwifi.
14. Orders are currently accepted, and shipments are made according to the schedule. Because the aluminum alloy shell customization needs to be based on the manufacturer's progress, the shell can be completed in 15 days at the earliest, so the delivery time cannot be guaranteed. Please ask if there is stock before placing the order.
15. Other instructions: This product uses the local oscillator signal and the external test signal to mix to obtain the difference frequency signal, and calculates 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), 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 increased the two parameters of magnification and displacement. Users can adjust the display waveform by themselves. The amplitude display is adjusted and calibrated.
