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.
50-ohm instrumentation coax
For timing, sensing, instrumentation and equipment-module links through 3 GHz.
Micro-coax construction
Reduces diameter and mass inside equipment, multi-coax connectors and dense assemblies.
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.
