## Features

- ★★★★★Its PCB board has been redesigned. 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.
