NOTE:
1. In dBm measurement mode, the decimal point of dBm is fixed between the second and third digits.
2. When in dBm measurement, the impedance is default at 600Ω. To change the impedance, press RANGE
button to select a proper impedance. The impedance can be chosen from:
4/8/16/32/50/75/93/110/125/135/150/200/250/300/500/600/800/900/1000/1200Ω.
