The Keysight 85099C is a 2-port RF electronic calibration module (ECal) that delivers NIST-traceable calibration accuracy to vector network analyzers across 300 kHz to 3 GHz. Operating with Type-F connectors and 75-ohm impedance, this module replaces time-consuming mechanical calibration procedures with fast, software-controlled electronic calibration via single USB connection.
Electronic calibration eliminates repetitive connector mating, reducing wear and operator interaction while maintaining accuracy comparable to traditional methods. The 85099C stores unique S-parameter data in onboard memory, enabling error-term calculation and supporting non-insertable device calibration. Directivity and source match performance vary across the frequency spectrum: directivity ranges from 43 dB to 50 dB, while source match spans 36 dB to 48 dB depending on operating frequency.
