Keysight N4691D Electronic Calibration Module (DC to 26.5 GHz)

Overview

The Keysight N4691D is a precision 2-port microwave electronic calibration (ECal) module designed for fast, accurate calibration of Keysight vector network analyzers. This variant features female-female 3.5 mm connectors and covers frequencies from DC to 26.5 GHz, with enhanced capabilities for broadband device modeling and time-domain analysis.

Performing a full two-port calibration takes less than half the time and connections required by traditional mechanical calibration kits. The operator simply connects the ECal module to the vector network analyzer via USB, and the firmware controls the calibration automatically, reducing operator error and minimizing wear on connectors and calibration standards.
