1.  The reading of dBm is indicated in decibels of power above or below 1 mW, or decibels of voltage above or below 1 V. The formula is calculated according
to the voltage measurement and specified reference impedance. Its accuracy is depended on the accuracy of the voltage measurement. See Decibel (dBV)
accuracy table below.
2.  Auto-ranging mode is used.
3.  The bandwidth is according to voltage measurement.
