The Siglent SHN900-TDR is the enhanced time domain analysis option for SHN900A vector network analyzers.

This option provides time-domain reflection, transmission analysis and eye diagram simulation analysis functions. Compared with ordinary frequency-domain analysis, it can quickly locate the fault point, determine the type of fault, can use the built-in virtual code generator to generate simulated eye diagrams, with jitter injection function to simulate the impact of the input signal with jitter on signal transmission.
