01 / CONFIGURATION DIRECTIONS
Select a configuration from the application boundaries
These configurations establish a practical discussion starting point. The final product requires a controlled specification based on interface, length, installation and validation conditions.
NMD-style rugged interface direction
For fast instrument-side adaptation and repeated connection; exact interface is confirmed from the analyzer.
Precision laboratory assembly
Length, connectors and handling rules defined for critical amplitude and S-parameter measurements.
Match a solution direction to the link target
Solution codes support early technical discussions by aligning protocol, construction, link boundaries and application in one view.
