Wi-Fi Test Tips Seven: Power ALL and Power Frame

Information

Power Frame: The average power of the data frame, the average value of the red line in the figure below Power Frame:-10.73dBm

Power Peak: The maximum peak power of all collected data, the maximum value of the green vertical line in the figure below Power Peak: -0.11dBm

PowerALL: The average power of all collected data, the PowerALL value in the figure below: -12.16dBm

Application scenarios:

PowerPeak: Mainly used to determine whether the DUT transmission power is overloaded.

PowerFrame: The actual transmit power of the DUT. If there is no PowerFrame power, please refer to PowerALL.

The value of Power ALL is related to the gap length of the input signal: the smaller the gap, the closer the difference between Power Frame and Power ALL, and vice versa, the greater the difference between the two.

The acquisition time in the above figure: 500us, gap: 10us,

Power Frame: -10.92dBm,

Power ALL: -11.50dBm
