AI Technical Summary
The prior art requires multiple measurements when checking the transmission characteristics of signal lines, resulting in low efficiency and high cost. Especially in the context of adapting to the 5G communication standard, the inspection requirements for signal lines are more stringent.
The vector network analyzer measures the reflection characteristics of the signal line, and combines the TDR conversion technology to judge the characteristic impedance, voltage standing wave ratio and transmission loss of the signal line. The transmission characteristics of the signal line are evaluated in just one measurement, reducing the cost of expensive instruments frequency of use.
It realizes efficient inspection of signal lines, reduces inspection costs, improves detection efficiency, and can meet the high-speed requirements of signal lines under the 5G communication standard.
