Feature: 1. REASONABLE DESIGN: This vector network analyzer is licensed under the LGPL and is based on the design for OwOComm for measuring higher frequency. 2. UNIQUE USER INTERFACE: The initial calibration data is not loaded at startup, and the calibration data will not be automatically inserted after the user changes the frequency. 3. DATA CALIBRATION: Every time you start the network analyzer and change the frequency, you must calibrate the data again or recall the calibration data. 4. WIDE APPLICATION: The network analyzer has a frequency range of 50kHz-3GHz and a scan speed of 100 points/second, has a wide range of applications. 5. EASY OPERATION: The analyzer kit is suitable for shortwave HF VHF UHF antenna, equipped with USB data cable, easy to connect and good stability.
