Description
Logarithmic Amplifier Digital RF Wattmeter Measurement 1MHz to 10GHz USB RF Power Meter Adjustable Attenuation Value
Product Description
HP362 is a radio frequency power meter, a fully monolithic 10GHz demodulation logarithmic amplifier based on continuous compression technology. The logarithmic amplifier provides a dynamic range of 50 dB, even at frequencies up to 100 MHz, it can still provide an error of ±l dB Dynamic range of 88 dB. The instrument sets the parameters through the upper computer, and has the advantages: simple structure, convenient use, stable performance, reliability, high sensitivity and fast measurement speed.
Application
● RF power measurement; ● Meter calibration;

Annotation
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 can’t be simpler, It means to express a very large (followed by a long string of 0s) or very small (a long string of zeros in front) in a short form. like: X=1000000000000000 (15 zeros in total) 10lgX=150dB X=0.000000000000001 10lgX=-150 dB dBm defines miliwatt. 0 dBm=1mw; dBw defines watt. 0 dBw = 10lg1 W = 10lg1000 mw = 30 dBm. DB always defines the power unit by default, 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 is true regardless of whether it is the control field or the signal processing field. For example, sometimes you can see the expression of dBmV.
