Condition: Used

A used accessory kit combining Rosenberger RPC-N precision connector components and a 7/16 DIN OSL (Open, Short, Load) calibration standard set, designed for use with cable and antenna analysers. Multiple sets are held; cosmetic appearance may vary between units.

Included items (as described):
• 7/16 DIN connector components
• OSL calibration standards (Open, Short, Load)
• RPC-N Rosenberger connector interface components

Rosenberger is a leading manufacturer of precision RF connectors, adapters, and calibration kits for vector network analysers (VNAs) and cable and antenna analysers (CAAs). The RPC-N is Rosenberger's precision N-type interface, intermateable with standard N connectors of the same impedance and designed for high-accuracy RF measurements.

The 7/16 DIN connector is a high-quality coaxial interface widely used in mobile communications infrastructure, offering low attenuation and excellent intermodulation performance. OSL (Open-Short-Load) calibration kits are essential accessories for cable and antenna analysers, enabling single-port vector error correction to ensure accurate return loss, VSWR, and DTF measurements.

OSL calibration is performed by sequentially connecting Open, Short, and Load standards at the measurement reference plane. This process characterises and removes systematic errors from the measurement system, allowing the reference plane to be moved to the far end of a test cable for accurate antenna and feedline characterisation.

Typical Specifications (7/16 OSL Calibration Kit):
Connector Type: 7/16 DIN
Impedance: 50 Ω
Frequency Range: DC to 7.5 GHz (typical for 7/16 interface)
Calibration Standards: Open, Short, Load (OSL)
Calibration Method: Single-port OSL (one-port vector error correction)
Load VSWR: < 1.012 (typical)
Electrical Length (Open/Short): 26.6 mm (typical)
Application: Cable and antenna analysers, VNAs
Connector Interface (RPC-N 50 Ω): DC to 18 GHz, Return Loss > 30 dB
Connector Interface (RPC-N 75 Ω): DC to 4 GHz, Return Loss > 36 dB
Standard: IEC 61169-16

Typical applications include mobile network infrastructure installation and maintenance, antenna and feedline return loss testing, VSWR measurement, and distance-to-fault (DTF) diagnostics on base station antenna systems.
