Keysight (Agilent) N7554A Electronic Calibration Module (ECal), DC-18 GHz, 2-Port

The Keysight (Agilent) N7554A is a 2-port electronic calibration module (ECal) designed for rapid VNA calibration across DC to 18 GHz. Using solid-state calibration technology, it eliminates the need for mechanical kits and multiple connector cycles, reducing setup time by up to 50% while minimizing connector wear. A single USB 2.0 connection to the VNA enables immediate calibration without external power supplies or additional instruments.

– Technical Specifications

• Frequency Range: DC to 18 GHz
• Ports: 2-Port configuration
• Impedance: 50 Ohm
• Connectors: 3.5 mm (female) or Type N
• Power Handling: Maximum +9 dBm applied power; performance degradation occurs above this threshold
• Calibration Technique: Electronic calibration (ECal) with NIST-traceable characterization

– Key Features

• Solid-state impedance states—programmable and highly repeatable across measurement cycles
• Single-connection calibration reduces mechanical wear on VNA connectors
• USB 2.0 micro-interface with native VNA firmware control
• Value-line economics: cost-effective to replace rather than recertify
• Compact, lightweight 2-port form factor

– Typical Applications

• Production-line VNA calibration requiring fast turnaround and minimal downtime
• Field service and maintenance where connector durability is critical
• Frequency-dependent impedance state verification up to 18 GHz
• Multi-port measurements on compatible analyzers

– Compatibility & Integration

Fully compatible with Keysight PNA-X, PNA, ENA, and PXI series vector network analyzers, plus FieldFox handheld analyzers. Operates as a firmware-controlled peripheral—no external calibration software or host PC required. NIST traceability ensures measurement integrity for regulated metrology environments.
