Rigol CK106A High-performance Network Analysis Calibration Kit

The Rigol CK106A is a mechanical OSL calibration kit engineered to eliminate systematic errors in network analyzer measurements across DC to 6.5 GHz. Designed specifically for Rigol's RSA3000N and RSA5000N series spectrum analyzers with integrated VNA capability, this 50 Ohm kit delivers the precision standards required for accurate S-parameter characterization. The kit comprises Type-N connectors in three mechanical standards: a fixed termination load with 0.98 minimum reflection coefficient and 0.3 dB insertion loss, an open circuit, and a short circuit.

Each component maintains consistent performance across the full frequency range, with the load achieving 1.2 VSWR. Operating from -55°C to +125°C, the CK106A meets RoHS compliance requirements and weighs 35 g, making it suitable for field and laboratory deployments. The fixed termination load measures Ø18.5×36.8 mm.
