N4431A 4-port RF Electronic Calibration (ECal) Module
This RF Electronic Calibration (ECal) module makes calibration of vector network analyzers fast, easy, and accurate.
This unit is a precision, single-connection calibration technique for your vector network analyzer.
Performing a full three or four port calibration takes less than half the time and number of connections using ECal versus mechanical cal kits.
Furthermore, the accuracy of the calibration is comparable between electronic and mechanical methods.
Traditional mechanical calibrations require intensive operator interaction, which is prone to errors.
With ECal, the operator simply connects the ECal module to the network analyzer and the software controls the rest.
Fast full 3 or 4 port calibration with a single connection
NIST traceable accurate calibrations
Reduced connector wear
USB interface for direct control with PNA and ENA series of network analyzers
Reliable solid state switching
Mixed connector option available (3.5mm, Type N 50ohms, and 7 16)
Firmware revision: 2.5
