1 Overview:
HP362 is a RF power meter. It is a completely monolithic 10GHz demodulation logarithmic amplifier based on continuous compression technology. The logarithmic amplifier provides a dynamic range of 50 dB, and can still provide an error of ± l dB even at frequencies up to 100 MHz. 88 dB dynamic range.
The instrument sets parameters through the host computer, which has the advantages of simple structure, convenient use, stable performance, reliability, high sensitivity and fast measurement speed.

P2 wiring definition:
CH1: RF signal input
annotation:
First, DB is a pure counting unit: for power, dB = 10 * lg (A / B). For voltage or current, the meaning of dB = 20 * lg (A / B) .dB can't be simpler,
It is to express a number that is very large (followed by a long string of zeros) or very small (preceded by a long string of zeros). Such as:
X = 1000000000000000 (15 in total)
10lgX = 150dB
X = 0.000000000000001
10lgX = -150 dB
dBm is defined as 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. At this time, 20lg is used.
This is true regardless of whether it is in the field of control or signal processing. For example, sometimes you can see the expression of dBmV.
