4.1, display measurement data
Interface display font:
The first line "RF-POW -51.2 dBm"
The second line "610uV 7nW"
Note: The signal dBm value, input voltage value, and input power are displayed respectively.
4.2. Set the RF power attenuation value
Interface display font:
The first line "RF Attenuator"
The second line "SUB 000dB"
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 and set the corresponding attenuation coefficient to read out the correct power parameters.
Wiring:
P1 wiring definition:
1. The positive pole of the power supply of the VDD module (7V~12V)
2. GND module's negative power supply
P2 wiring definition:
1, FX is not used
2. RF signal input
3, GND negative pole of power supply
Annotation:
First of all, 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) is expressed in a short form. Such as:
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 applies to both the control field and the signal processing field. For example, sometimes you can see the expression of dBmV.
