Keysight Technologies Inc. Multiport ECAL module DC to 20 GHz
The Keysight N7564A is a 4-port Multiport Electronic Calibration (ECal) Module designed for vector network analyzers (VNAs). It covers a frequency range from DC to 20 GHz and enables fast, repeatable, and convenient calibration of multiport test setups. The N7564A automates the calibration process, reducing operator errors and setup time compared to manual calibration kits. It is USB-controlled and compatible with Keysight ENA and PNA series VNAs. The module is factory characterized for high accuracy and supports full 2-, 3-, and 4-port calibrations, making it ideal for multiport device measurements in R&D and manufacturing environments.
