Q3. How can I use Spectrum Analysis
to find the appropriate channel for the
devices?
1. Log in to PharOS, on the 'WIRELESS' page, you can find the 'Spectrum
Analysis' button as shown in the figure below. Click the button.
2. The following window will pop up. Click 'Yes' and you will then get
into the Spectrum Analysis page.
3. Select the 'Frequency Range' and click the 'Start' button, the PharOS
will begin to analyze the power of the frequency. Watch the curves
for a period of time, and then click 'Stop' . Mark the relatively low and
continuous part of the average curve, and note the corresponding
frequency range.
Here we take the figure below as an example.
