HP368 is a radio frequency power meter. The meter is operated by pressing the keys. Its advantages: simple structure, convenient use, stable performance, reliability, high sensitivity and fast measurement speed.
Typical Applications:
● RF power measurement;
● Meter calibration;
Technical parameters:
● Measuring power range: -60～+7 dBm (External RF attenuator can be extended to 100dBm)
● Measurement power resolution :0.1 dBm
● Measuring frequency range: 50Hz～3800 MHz
● Measuring power : 1nW～1W
● Working voltage: 7～12 VDC
● Working current <50 mA
● Working temperature: -40℃～65℃
● Storage temperature ;-40℃～65℃
● Size: 55*45*10 mm (LxWxH)
LCD interface display and operation instructions:
(1) Unit: dBm;
(2) Key description:
FUN: Function key; MODE: Change interface; SEL: Self-up key or self-decrement key;
4.1, display measurement data
Interface display font:
The first line "RF-POW -65.5 dBm"
The second line "110uV 0nW"
Note: Display the signal dBm value, input voltage value, and input power respectively.
4.2. 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) Display SUB for subtraction, display ADD for addition. (Long press the FUN key to save the set dB value)
SEL: Self-increasing key or self-decreasing key;
4.3. Set the value of the measurement frequency (function: modify the radio frequency power of different frequencies)
Interface display font:
The first line "Measuring freq"
The second line "SUB 00.0GHz"
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 frequency 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.
Terminal Description:
1 VDD module's positive power supply (7V~12V)
2 GND The negative pole of the power supply of the module
1 RF radio frequency signal input
2 GND Power negative
About dB Notes
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 could not be simpler, that is, a very large (followed by a long string of 0s) or a very small (preceded by a long string of 0s) number is expressed relatively shortly. 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.
