Digital RF Power Meter 1MHz to 10GHz -50 to 0dBm RF Signal Measuring Meter

Intelligent Digital RF Power Meter 1MHz to 10GHz -50 to 0dBm RF Signal Measuring Meter Module 

Technical Parameters

Operating Instruction

● Unit: dBm

● Button functions:

[FUN]: function button; [MODE]: switching interface; [SEL]: Automatic adding or Subtracting button

1.1 Display data measured

Screen interface characters display

First row: " RF-POW  -51.2 dBm   "

Second row:  "  610uV    7nW "

Explanation: -51.2dBm refers to signal dBm value;  610uV refers to input voltage value; 7nW refers to input power value.

1.2 Set RF power Attenuation value

Screen interface characters display:

First row: "RF Attenuator "

Second row: "SUB    000dB  "

Button operation:

[FUN]: Function button, select adding or subtracting option, if displays SUB, it refers to subtract value; if displays ADD, it refers to adding value. Long pressing FUN button can save the pre-setting dB value.

SEL: Auto-adding or Auto-subtracting button

* Adding different RF attenuator, user set related attenuation value, the RF power meter can read correct power parameters.

Terminals Definition

Note:

dB is a counting unit, if used it in power, dB = 10*lg(A/B). Using it in voltage or current, dB = 20*lg(A/B). dB is used to simply and briefly display a very large or small number (e.g.: a number has many 0, like 10000000.... or 0.00000001).

Examples:

X=1000000000000000 (15 x 0) can be displayed into 10lgX= 150dB

X=0.000000000000001 (15 x 0) can be displayed into 10lgX= -150dB

dBm is used to definite miliwatt, 0 dBm=1mW

dBw is used to definite watt, 0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm

No matter in process controlling filed or signal processing filed, dB is usually used to definite power unit, count in 101g. While in some conditions, signal amplitude is used to describe power, in that conditions, it counts in 201g.
