The Keysight (Agilent) N4691B electronic calibration (ECal) module makes the calibration of vector network analyzers fast, easy and accurate. The N4691B ECal module is now easily controlled by one of two methods depending on the network analyzer. The Keysight (Agilent) PNA and ENA series of network analyzers controls the module directly via the USB interface. The N4691B modules can also be controlled via an 85097B interface kit when used with a Keysight (Agilent) 8753E/ES/ET or 8720D/ES/ET. (This requires a special parallel cable and firmware Rev. 7.74).

Traditional mechanical calibrations require intensive operator interaction, which is prone to errors. With the N4691B electronic calibration module, the operator simply connects the N4691B module to the network analyzer and the software controls the rest.
