Features: According to the license agreement for LGPL, based on the design for OwOComm, SAA2 is a portable 3GHz vector network analyzer. It does not load initial calibration data at startup and does not automatically insert calibration data after users change frequency. Calibration data must be recalibrated or recalled after each startup and frequency change. Please read instruction manual carefully before use to avoid damage to the device. VNA-QT software compatible system for Linux, for Windows (7+), for Mac OS planned.
