– Compatibility & Integration

Designed for use with 75 Ohm Type-N equipped network analyzers and RF measurement systems interfacing with 75 Ohm BNC-terminated devices. The kit supports direct connection between analyzer ports and BNC-connector equipment without impedance discontinuity. Earlier production designated as Hewlett-Packard or Agilent Technologies maintains identical functionality. This product is obsolete per manufacturer designation by Keysight.
