RF-Power8000 1Mhz-8000Mhz – OLED RF Power Meter -55dBm ~ -5dBm
Adjustable Attenuation Value

It’s based on AD8319

Measuring power range: -45 ~ + 5 dBm (external RF attenuator can be extended to 100dBm)
Measurement resolution: 0.1 dBm
Measurement frequency range:  1Mhz-8000Mhz
Measured power: 1nW ~ 2W Working voltage: 5V DC (can work MICRO-USB powered)
Working current: <50 mA
Working temperature: -40 ℃ ~ 65 ℃
Storage temperature: -40 ℃ ~ 65 ℃ Size(L*W*H):50 x 50 x 25 mm

Product application:
1. Low RF power measurement
2. Low calibration instrument  

0.96 Inch OLED display, PC to read data and Settings, can set the frequency point, preset attenuation, simple structure, convenient use, stable performance, reliable, high sensitivity and fast measurement, etc.  

1. Set by the upper machine frequency value
2. Instrument above contains four buttons, respectively is: up, down, left, right, sure touch four switches. Is to move the cursor around with, is add and subtract values with up and down.  

RF Common Sense Science:
1. dB is a pure count of unit:
For power, dB = 10 * lg (A / B).
For voltage or current, dB = 20 * lg (A / B).
2. dBm is defined miliwatt (mW).
0 dBm = 1mw; dBw defined watt. 0 dBW = 10lg1 W = 10lg1000 mw = 30 dBm. 3. dB power units are always defined by default, to 10lg for scoring.
Of course, some cases may signal strength (Amplitude) to describe the work and power, this time with 20lg for scoring.
Whether in the field or control signal processing field like this.
For example, sometimes you can see the expression dBmV.
