Structural scheme of the measuring system The measuring system is divided into a system with a spectrum analyzer, shown in figure 1. 3, and a power metering system as shown in figure 2. 4. The first is usually used to measure small and medium power levels and analyze the spectrum.
The measuring system is divided into a system with a spectrum analyzer, shown in figure 1. 3, and a power metering system as shown in figure 2. 4. The former is commonly used for measuring small to medium power levels and spectrum analysis; the latter is specifically designed for precision power measurement.

All instruments must be securely connected to a dedicated grounding line; it is strictly forbidden to use the power grid neutral as a protective grounding for the measuring system.
At the output port of the power amplifier, it is recommended to install an isolator;
The value of the attenuator must be selected correctly; it must be ensured that the power entering the measuring device is in a safe range;
The system must be fully heated and calibrated.
The operator must be equipped with an antistatic bracelet;
environmental conditions must meet the requirements of the measurement method.
