RF common sense science:
dB is a pure counting unit:
For power, dB = 10*lg(A/B).
For voltage or current, dB = 20*lg(A/B).
dBm defines miliwatt (milliwatt). 0 dBm=1mw;
dBw defines watt. 0 dBw = 10lg1 w = 10lg1000 mw = 30 dBm.
By default, dB always defines the power unit, which is calculated as 10lg. Of course, in some cases, signal strength (Amplitude) can be used to describe work and power. In this case, use 20lg as the meter. This applies to both the control field and the signal processing field. For example, sometimes you can see the expression of dBmV.
Interface operation:
6.1 Interface display description
FreqX:
The frequency point to be tested, the default is Freq0, and 8 groups of frequently used frequency points (Freq1-Freq8) can be stored, which can be set by pressing the key or supporting the upper computer.
Level:
The power value in dBm corresponding to the current frequency point
Power:
The current frequency point corresponds to the power value in uW or mW
OffetX:
The power correction value, the default is Offet0, and 8 groups of correction values corresponding to the frequency points (Offet1- Offet8) can be stored, which can be set by pressing the button or supporting the upper computer
