Product description：
1. Click on the test, the result shows the frequency, power, and frequency offset value of the current Bluetooth device, the approximate time is 1.5S
2. Click calibrate to automatically calibrate the current frequency, write the value of the calibration number to the Bluetooth device, and display the frequency, power, and frequency offset values of the Bluetooth device after calibration. The approximate time is 5s.
3. The frequency range is selected according to the actual product standards, and the strict requirements are ±10kHz, generally ±20kHz.
4. The power range setting mainly filters equipment with low power
5. It can be tested by antenna induction. The input sensitivity of the SA4400 simple spectrum is about-70dBm, the maximum effective power of the input is 0dBm, and the maximum power of the port is 0dBm. If the direct connection power is too large, please add an attenuator.
