Abstract

The invention relates to a network analyzer measuring device and system, which is characterized in that an excitation signal output by an output port of a network analyzer flowing through a measured piece is converted into an electromagnetic wave signal through a microwave radio frequency device, and the electromagnetic wave signal is received by a signal detection device and is converted into a reflection signal; and a microwave measuring instrument performs optimization frequency reduction processing on the reflection signal to obtain a feedback signal and sends the feedback signal to an input port of the network analyzer. On the basis, the microwave measuring instrument is used for performing power amplification on the reflection signal and removing a noise signal, and the low-frequency signal output to the input port of the network analyzer is high in signal sensitivity and high in detection speed, so that the sensitivity and the precision of subsequent measurement by the network analyzer are improved.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a network analyzer measuring device and system. Background technique [0002] Network analyzer is a comprehensive microwave measuring instrument that can scan and measure within a wide frequency band to determine network parameters. Its input and output terminals are connected to antennas and can be used as signal transmitting and receiving measuring equipment, and can also be used as measuring equipment. Among them, the application of network analyzers in the field of microwave measurement is becoming more and more important. With the development of technology, the hardware level of the system is no longer the main reason affecting the test accuracy of the network analyzer. If you want to improve the test progress of the network analyzer, simply improving the hardware performance will bring more difficulty in the design of the network analyzer. and cost increases....
