Time Domain Analysis (TDA)

Time-domain analysis refers to analyzing the stability, transient and steady-state performance of the control system according to the time-domain expression of the output quantity under a certain input.

The 3671 series vector network analyzer can realize the switching between the frequency domain and the time domain of the measurement results, obtain the similarity and correlation of the signal waveform at different times, and obtain the characteristic parameters reflecting the operating state of the mechanical equipment. This function can be used to identify discontinuities in devices, fixtures or cables to realize accurate fault location.
TDR Option

The advanced time-domain analysis option of the 3671 series vector network provides a virtual eye pattern and analysis function based on S parameter. The output unit of the simulation code type is used to generate the data bits of 0 and 1 change, convolve the simulation code type with the time-domain impulse response of the tested part, and obtain the virtual eye map after superposition.

Depending on the different high-speed digital communication standards, TDR options can be used for high efficiency Pass/Fail tests using predefined eye pattern templates. And TDR option can apply Jitter, noise and other interference on the simulation eye pattern.
