Network Analyzer

• What is a network analyzer?

The network analyzer is an instrument that measures the network characteristics of the device by measuring the amplitude and phase response of each port on the network to the frequency/power sweep test signal. It combines various technologies such as spectrum analysis, signal generation, and signal separation. It is known as the “King of Instruments”. It is an essential test and measurement instrument in the radio frequency and microwave field, and is the basic form of special instruments in many industries.

• What are the functions of a network analyzer?

The network analyzer products can measure multi-port vector S parameters and implement various levels of system error calibration. They are highly integrated RF microwave instruments and are used in basic industries and fields such as chip testing, microwave devices, materials science, and electronic communications, such as filters, antennas, and power amplifiers.

• Verification method

There are two common verification methods:

• • Transmission, Reflection, Line (TRL)
  • Short circuit, open circuit, load, penetration (SOLT)

They are different combinations of impedance and transmission measurements that analyze cables and test fixtures for verification.

These calibration techniques link a standard set of known characteristics to the measurement setup of the device under test. Cables and connectors are calibrated by comparing measured values ​​with standard values.
