Keysight (Agilent) N4696B Electronic Calibration Module, 300 kHz to 18 GHz

The Keysight N4696B Electronic Calibration Module delivers fast, accurate two-port VNA calibration across 300 kHz to 18 GHz in a single connection. This USB-controlled ECal unit replaces mechanical calibration kits, eliminating operator error while reducing setup time and connector wear. Solid-state switching ensures reliable performance with NIST-traceable accuracy comparable to traditional standards.

Direct integration with Keysight PNA and ENA series analyzers - controlled from the instrument's front panel without external PC - makes it ideal for automated test environments and field applications where measurement repeatability and minimal downtime are essential.
