1PC Power meter 1 MHz ~ 10ghz-50 ~ 0dbm can set RF power attenuation value

Description

1PC Power meter 1 MHz ~ 10ghz-50 ~ 0dbm can set RF power attenuation value
I. overview:
HP363 is a radio frequency power meter, which is operated by pressing keys.
Its advantages are simple structure, convenient use, stable performance,
reliability, high sensitivity and fast measurement speed.
II. Application:
● RF power measurement;
● Instrument calibration;
Three, technical parameter table:
1 Measurement power range:-50 ~+0 dBm (external RF attenuator can be extended to 100dBm)
2 Measurement power resolution: 0.1 dBm
3 Measurement frequency range: 1 ~ 10000 MHz
4 measuring power: 1nW～1mW
5 working voltage: 7 ~ 12 VDC
6 operating current: < 50 mA
7 working temperature:-40℃ ~ 65℃
8 storage temperature:-40℃ ~ 65℃
9 dimensions: 55*45*10 mm length x width x height
Four, interface display and operation instructions:
(1) Unit description: dBm;
(2) Key Description:
FUN: function key;  MODE: set up exchange interface;  SEL: Self-plus or Self-minus key;
4.1. Display measurement data
Interface display font:
First row "RF-POW -51.2 dBm"
Second line "610U7NW"
Note: Signal dBm value, input voltage value and input power are displayed respectively.
4.2. Set RF power attenuation value
Interface display font:
First line "RF Attenuator"
In the second line, "SUB 000dB"
Key operation:
FUN: function key;  (Select the direction of addition and subtraction) Displays
SUB as minus and ADD as plus.  (Press FUN key long to save the set dB value)
SEL: Self-plus or Self-minus key;
Note: Different RF power attenuators are externally connected, and the correct
power parameters will be read out when the corresponding attenuation coefficient is set.

Comments:
First, dB is a pure counting unit: for power, dB = 10*lg(A/B).  For voltage or current, dB = 20*lg(A/B).  In fact, the meaning of dB is as simple as expressing a very large number (followed by a long string of zeros) or a very small number (preceded by a long string of zeros).  For example:
X = 10000000000000 (15 of 0)
Can be expressed as: 10lgX=150dB
X=0.000000000000001
Can be expressed as: 10lgX=-150 dB
DBm is defined as miliwat (milliwatt).  0 dBm=1mw；
DBw defines watt.  0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm。
DB always defines unit of power by default, based on 10lg.  Of course, signal strength can be used to describe work and power in some cases, and 20lg is used at this time.  This is true in both control and signal processing fields.  For example, sometimes you can see the expression of dBmV.
