- LibreVNA-Dedicated Calibration Kit: LibreCAL is a 4-port electronic calibration kit designed for LibreVNA, covering a frequency range from 9 kHz to 6 GHz. 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
- 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
- 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
- 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
- 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
- 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
- Package Includes: 1* LibreCAL, 4* SMA-JJ RG405 RF Cable, 1* USB Type-C Data Cable, 1* Storage Bag. We've included all the necessary cables and a bag so you're ready to go. For any product-related questions, support is available upon request
