Keysight (Agilent) N7555A

The Keysight N7555A is a 2-port electronic calibration module designed to enable fast, accurate VNA calibration across DC to 26.5 GHz. This value-line ECal module eliminates lengthy setup times associated with mechanical calibration kits by delivering zero wait-time calibration through direct USB 2.0 micro-interface control. The N7555A integrates with Keysight’s PNA-X, PNA, ENA, and PXI series VNAs as well as FieldFox handheld analyzers, providing a compact, lightweight solution for on-site and lab-based network analysis.
