• Short calibration standard
• 50-ohm load(s)
• RPC-N (Type-N) connector components

This accessory kit is a generic/unbranded professional RF accessory set designed for use with cable and antenna analyzers. Products of this type are widely used across the telecommunications, cellular infrastructure, and RF engineering industries to support field calibration and connector adaptation on handheld and bench-top cable and antenna test instruments.

The 7/16 DIN connector (also known as the L29 connector) is a 50-ohm threaded RF coaxial connector standardised to IEC 61169-4, widely used in cellular network antenna systems and high-power RF applications due to its superior passive intermodulation (PIM) performance. RPC-N (Type-N) connectors are a common 50-ohm coaxial interface used as the primary test port on most cable and antenna analyzers.

An Open-Short-Load (OSL) calibration kit is used to establish a measurement reference at the test port of a cable or antenna analyzer. By sequentially connecting the open, short, and 50-ohm load standards, the instrument corrects for systematic errors and moves its reference plane to the point of calibration, enabling accurate VSWR, return loss, and distance-to-fault (DTF) measurements.

Adapter sets of this type allow the test port of an N-connector-equipped analyzer to interface with 7/16 DIN-terminated coaxial cables and antenna feedlines, which are the standard connection type on most cellular base station antenna systems.

Typical Kit Contents (generic):
• Open calibration standard
• Short calibration standard
