Time Signal Processing / TDR Cross-Probing
Macros MacrosTime Signal ProcessingTDR Cross-Probing
This macro helps to identify locations in the structure based on TDR
impedance profile.
Assumptions:
The
structure has to be simulated with transient solver, using a short
gaussian (!) pulse (Note: a step function as excitation can not
be used together with this macro.) A
time
domain power flow monitor. needs to be defined,
whose time sampling rate (time step width)
determines the spatial resolution, which can be achieved with the
cross probing. Between these two samples an interpolation needs to be
performed. Finally
a TDR Result Template needs to be defined via Template
Based Post Processing -> 1D
Once all above conditions are fulfilled
and all result data is calculated, the macro can be applied.
TDR time
Specify the time of the TDR pulse you are interested
in.
Note: Please ensure, that the time you enter
corresponds to the TDR delay, which starts with 50% of the pulses maximum
at t=0.
Power flow
Select a certain power flow monitor from the
drop down list. This allows for instance to probe from different ports.
Cross-probe to Structure
When pressing this button, the macro analyzes
the power flow monitor and back annotates the TDR time to the structure.
After closing the dialogue, a point in the structure is highlighted:
