With simple but practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software from PC software. - ★★★★★With improved frequency algorithm, it supports the odd harmonic expansion of the si5351 and supports 900MHz measurement frequency. - ★★★★★The si5351 is designed with a metal shield to reduce external interference and improve measurement accuracy. It can directly output 50K-300MHz frequency, and the dynamic performance is better than 70dB. Its extended 300M-600MHz band provides better than - ★★★★★A DIY vector network analyzer with a 2.8-inch touch screen and 400mAh of power, it can be used offline within 2 hours. If you want to extend the test time, you can connect it to an additional mobile power source or contact us for more capacity. - ★★★★★For testing with TX / RX, you can get the full set of parameters for S11 and S21. All you have to do is replace the connection cable in the receiving port and the sending port. ## Images ![Tangxi 50KHz-900MHz Vector Network Analyzer Kit, 2.8-inch Digital LCD Touch Screen DIY Vector Network Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart - Image 1](https://images-na.ssl-images-amazon.com/images/I/618I2SIQ8EL.jpg) ![Tangxi 50KHz-900MHz Vector Network Analyzer Kit, 2.8-inch Digital LCD Touch Screen DIY Vector Network Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart - Image 2](https://images-na.ssl-images-amazon.com/images/I/61qQ3j9h0OL.jpg) ![Tangxi 50KHz-900MHz Vector Network Analyzer Kit, 2.8-inch Digital LCD Touch Screen DIY Vector Network Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart - Image 3](https://images-na.ssl-images-amazon.com/images/I/71o4NkSSqVL.jpg) ![Tangxi 50KHz-900MHz Vector Network Analyzer Kit, 2.8-inch Digital LCD Touch Screen DIY Vector Network Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart - Image 4](https://images-na.ssl-images-amazon.com/images/I/61M9lEC9r0L.jpg) ![Tangxi 50KHz-900MHz Vector Network Analyzer Kit, 2.8-inch Digital LCD Touch Screen DIY Vector Network Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart - Image 5](https://images-na.ssl-images-amazon.com/images/I/61WGMYAql0L.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/200222739-tangxi-50khz-900mhz-vector-network-analyzer-kit-2-8-inch](https://www.desertcart.tn/products/200222739-tangxi-50khz-900mhz-vector-network-analyzer-kit-2-8-inch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-11*
