It works directly with LibreVNA-GUI for one-click calibration.This kit is compatible exclusively with LibreVNA and is not supported on other VNA models \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e All-in-One 4-Port Calibration: Built-in Open, Short, Load, and Through standards allow full 4-port VNA calibration in one simple process. Compared with traditional mechanical calibration, it reduces setup steps and helps improve testing efficiency and repeatability \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Reliable Calibration Performance: LibreCAL is calibrated using precision reference standards. S11 directivity is better than 50 dB below 3 GHz and better than 40 dB above 3 GHz. For higher accuracy needs, mechanical calibration standards can be used as a supplement. Electronic calibration does not include isolation calibration. Built-in calibration data is currently supported only by LibreVNA \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Built-in Calibration Data: Each LibreCAL unit comes with factory calibration data, including 18 calibration coefficients per set (4-port reflection standards and 6 Through standards). You can also create your own calibration sets and access them via SCPI API, export them through LibreVNA-GUI, or read them directly via USB storage \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Dual Control Modes: Supports both manual button control and USB software control. Automated operation is recommended via LibreVNA-GUI or Python scripts. In manual mode, each port can be configured directly using buttons, and settings are saved until overwritten by USB control or device restart, reducing repeated setup \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Temperature-Stable Design: A built-in heater and temperature sensor keep the device stable during operation, helping reduce the impact of environmental temperature changes and ensuring more consistent measurement results \u003c\/span\u003e\u003c\/li\u003e \u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003e Package Includes: 1* LibreCAL, 4* SMA-JJ RG405 RF Cable, 1* USB Type-C Data Cable, 1* Storage Bag.
