How to use vector network analyzer to test cables with non nominal 50 Ω

This application test aims at the test of non nominal 50 Ω cable, including coaxial, twisted pair, differential high-speed data line, including impedance parameters, s parameters (insertion loss, standing wave, Smith diagram, etc.), and can also draw eye diagram. According to the performance of the cable, such as frequency range, length, difference or not, time-domain […]

How to test the signal integrity and how to realize it

There are many means of signal integrity test, some of the main means are waveform test, eye diagram test, Jitter Test and so on. At present, the widely used signal integrity test means should be waveform test, that is, using oscilloscope to test waveform amplitude, edge and burr. Through testing waveform parameters, we can see […]

Using four analysis methods of spectrum analyzer to observe signal quality

Wireless communication often needs to use spectrum analyzer to demodulate the signal and analyze the signal quality. There are usually four methods for analysis: IQ constellation diagram, IQ eye diagram, symbol table and bit error rate table. Today we will introduce how these four analysis methods can help us observe the signal quality. 1、 IQ […]
