- Maximum access signal: 10dB.
- Working mode: superheterodyne scanning spectrum analyzer, single scanning time 800ms.
- With built-in battery
- Product specifications: 145mm*70mm*30mm. Weight: 200g.
- Use range: walkie-talkie, toy remote control, 2.4G wifi.
- It uses local oscillator signal and external test signal to mix to obtain the difference frequency signal, and calculate the external test signal amplitude through a detector. Using a high-precision VCO signal source, the heterodyne signal frequency can be measured very accurately. Since 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 added magnification and displacement parameters. Users can adjust the displayed waveform by themselves. The amplitude display can be adjusted and calibrated.
