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 (480×800) 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.
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 access signal: 10dB.
10. Working mode: superheterodyne scanning spectrum analyzer, single scanning time 800ms.
11. The internal integrated battery charging circuit, By default, usb is used for power supply, and please note battery is not included (installation instructions for batteries are provided).
12. Product size: 145mm*70mm*30mm
13. Use range: walkie-talkie, toy remote control, 2.4Gwifi.
14. Other instructions: This product uses the local oscillator signal and the external test signal to mix to obtains 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), 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. So 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.
