Manufacturer number: N4431D
The Keysight N4431D Electronic RF Calibration (ECal) module makes calibrating Keysight vector network analyzers fast, easy and accurate. The N4431D is a precision 4-port ECal module that supports a variety of connectors including Type-N, 3.5 mm, 7-16 and 4.3-10 connectors and can be mixed up to 13.5 GHz. Choose either female-female, male-male or female-male.
The N4431D extends the calibration frequency range down to start at DC, which is beneficial for modeling wideband devices or time domain and signal integrity analysis using extended time domain analysis on Keysight network analyzers.
This ECal module is an ideal solution for calibrating vector network analyzers. Performing a full 4-port calibration requires less than half the time and number of connections compared to traditional mechanical calibration kits. The operator simply connects the ECal module to the vector network analyzer via USB and the firmware controls the rest, reducing the risk of operator error. Connector wear and tear is also reduced, lowering repair costs for test port connectors and calibration standards.
