EverythingRF featured the W2604A from Withwave, a 4-port automatic calibration module that operates from 100 kHz to 26.5 GHz. It is designed to operate as a host system for automated measurement and calculation of calibration coefficients. These features enable fast and easy calibration of vector network analyzers (VNAs). The module is compatible with Keysight PNA Series, R&S ZVL/ZVA/ZVT Series, Anritsu ShockLine Series, and CMT Planar Series, and supports full 4-port calibration. It provides directivity of more than 42 dB, source match better than 40 dB, and load match over 40 dB. 

The W2604A also employs an internal thermal compensation mechanism to improve calibration accuracy over an operating temperature range from 20°C to 30°C. This calibration module allows for easy firmware updates through an embedded OS, with no requirement for an external PC or software. It can be controlled remotely using LAN and USB interfaces. This automatic calibration module can be powered via a USB port. It is available as a module and has a 3.5 mm (female) connector. https://www.everythingrf.com/products/vna-calibration-kits/withwave/841-704-w2604a
