Welcome to our store! 1. Suitable for Original Equipment: Vector network analyzer units are designed to fit original equipment and can be exported via PC software to various radio design and simulation software Touchstone (snp) files. 2. High Accuracy: The VHF vector network analyzer features enhanced frequency algorithms that can support measurement frequencies up to 900MHz using si5351's odd harmonic extension, designed with a metal shield that reduces external interference and improves measurement accuracy. 3. Extended Frequency Band: The antenna analyzer provides better than 70dB dynamic range in the 50KHz-300MHz band through the direct output of si5351, the extended 300M-600MHz band can provide better than 50dB dynamic range, and the 600M-9000M band better than 400dB. 4. Wires: Network Analyzer uses platinum contact wires to reduce the number of connection points for faster response to changes. The ceramic printed circuit board is protected by silicone for excellent resistance to temperature changes and automotive vibrations. 5. Handheld: The vector network analyzer is handheld and includes a 2.8-inch touchscreen and a 400mAh battery for 2 hours of offline use. For longer measurements, connect an external power source or make a larger battery version. The TX or RX method can measure the entire S11 and S21 parameters. You need to manually change the transceiver port wiring to get S12 and S22.
