Feature: 1. This product is a DIY product that provides perfect vector network measurement capabilities, compact and handheld, with 4-inch display. 2. The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency upto 1.5GHz. The 50K-300MHz frequency range of the si5351 direct output provides betterthan 70dB dynamic, The extended 300M-900MHz band provides betterthan 60dB of dynamics, and the 900M-1.5GHz band is betterthan 40dB of dynamics. 3. The default firmware main function is used for antenna performances measurement. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the TransceiverPort wiring, 4. Using PCsoftware NanoVNASaver, it can connect to aNanoVNA and extracts the data for display on a computer, and for saving to Touchstone files. We can export Touchstone (snp) files for various radio design and simulation software through PC software. 5. The metal material is designed to reduce the external interference and improve the measurement accuracy.
