The electronic calibration (ECal) is a precision, four-connection calibration technique for your vector network analyzer. ECal modules use fully traceable and verifiable electronic impedance standards.
The N4431A modules are state-of-the-art, solid-state devices with programmable and highly repeatable impedance states. ECal modules are transfer standards that provide consistent calibrations and eliminate operator errors while bringing convenience and simplicity to your calibration routine. Consistent calibrations provide consistent measurements.
ECal replaces the traditional calibration technique, which uses mechanical standards. With mechanical standards you are required to make numerous connections to the test ports for a single calibration. These traditional calibrations require intensive operator interaction, which is prone to error. With ECal, a full one- to four-port calibration can be accomplished with a single connection to the ECal module and minimal operator interaction. This results in faster and more repeatable calibrations.
The ECal modules are transfer standards capable of transferring the factory calibration accuracy to your network analyzer. They are characterized by Agilent using a precision calibration technique (similar in accuracy to TRL) that is traceable to the National Institute of Standards and Technology (NIST). Each calibration modules unique S-parameter data is stored in the modules memory. During calibration, ECal uses this data to calculate the error terms for your network analyzer. All measurements on either insertable or non-insertable devices are traceable to NIST.
The N4431A MW electronic calibration (ECal) module makes calibration of vector network analyzers fast, easy and accurate. The RF ECal system is now easily controlled by one of two methods depending on the network analyzer. The PNA and ENA series of network analyzers controls the module directly via the USB interface.
ECal is an ideal solution for calibrating network analyzers. Performing a full two-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.
