Installation Instructions
Interface display and operation instructions:
(1) Unit description: dBm; (2) Key description: FUN: function key; MODE: change interface; SEL: self-up key or self-decrement key; a, display measurement data Interface display font: The first line "RF-POW -65.5 dBm" The second line "110uV 0nW" Note: The signal dBm value, input voltage value, and input power are displayed respectively. b, Set the RF power attenuation value Interface display font: The first line "RF Attenuator" The second line "SUB 00.0dB" Key operation: FUN: Function key; (select the direction of addition and subtraction) SUB is displayed for subtraction, and ADD is displayed for addition. (Long press the FUN key to save the set dB value) SEL: Self-increasing key or self-decreasing key; Note: Connect different RF power attenuators, set the corresponding attenuation coefficient, and read the correct power parameters.

Annotation
First, dB is a pure counting unit: for power, dB = 10*lg(A/B). For voltage or current, dB = 20*lg(A/B). The meaning of dB can't be simpler, that is, a very large (followed by a long string of 0s) or very small (a long string of zeros in front of it) is expressed in a short form. like: X=1000000000000000 (15 zeros in total) It can be expressed as: 10lgX=150dB X=0.000000000000001 It can be expressed as: 10lgX=-150 dB 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 is true for both the control field and the signal processing field. For example, sometimes you can see the expression of dBmV.
