The Agilent 85092C RF 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 Agilent PNA and ENA series of network analyzers controls the module directly via the USB interface. The modules can also be controlled via an 85097B interface kit used with an Agilent 8753E/ES/ET or 8720D/ES/ET.
