The Keysight 85093A RF Electronic Calibration (ECal) Module is a solid-state calibration instrument that delivers fast, accurate automated calibration for vector network analyzers using 3.5 mm connectors. Unlike traditional mechanical kits, this module enables full 2-port calibration with a single connection, eliminating manual handling errors and improving measurement repeatability. Built-in traceable electronic standards and stored S-parameter data calculate VNA error terms with accuracy comparable to mechanical methods but with minimal operator interaction and significantly reduced calibration time.
Technical Specifications

– Key Features
• Single-connection full 2-port calibration eliminates multi-step mechanical procedures
• Solid-state switching technology ensures high reliability and reduced connector wear
• Stored S-parameter data enables error term calculation without external reference standards
• NIST-traceable calibrations provide measurement confidence across the 30 kHz to 6 GHz range
• Direct VNA integration removes PC dependency for routine calibration workflows
• Ideal for non-insertable device characterization (female-connector test ports)
– Typical Applications
Electronic calibration for precision VNA measurements in RF and microwave component testing, system validation, and in-situ device characterization where speed and repeatability outweigh traditional kit-based approaches.
– Compatibility & Integration
Fully compatible with Keysight PNA and ENA series analyzers. Operates via direct USB control from VNAs or through Windows 95/NT 4.0 PC platforms for legacy system integration. The module replaces traditional mechanical calibration kits while maintaining measurement accuracy across the supported frequency band.
