4、 Interface display and operation instructions:

(1) Unit description: dBm;

(2) Key Description:

FUN: function key; MODE: Change the interface; SEL: Self adding or self reducing keys;

4.1 Display measurement data

Interface display font:

The first line reads "RF-POW -80.3 dBm"

The second line "20uV 0nW"

Annotation: Display the signal dBm value, input voltage value, and input power separately.

4.2. Set 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) Display SUB as subtraction and ADD as addition. (Long press and hold the FUN key to save the set dB value)

SEL: Self adding or self reducing keys;

Note: By connecting different RF power attenuators externally and setting the corresponding attenuation coefficient, the correct power parameters can be read out.
