Vector Network Analyzer 50KHz to 300MHz MF HF VHF UHF Antenna Analyzer for Measuring S Parameters Phase Delay Features: 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: VHF vector network analyzer has improved frequency algorithms that can support measurement frequencies up to 900MHz using the si5351's odd harmonic extension, designed with a metal shield that reduces external interference and improves measurement accuracy. 3.Extended Frequency Band: Antenna Analyzer provides better than 70dB of dynamics in the 50KHz?300MHz band through the direct output of the si5351, the extended 300M?600MHz band can provide better than 50dB of dynamics, and the 600M?900M band better than 40dB of dynamics. 4.Threads: Network Analyzer utilizes platinum connector threads to reduce the number of connection points for faster response to changes. The printed circuit board made of ceramic is protected by silicone for excellent resistance to temperature changes and vehicle vibration. 5.Handheld: Vector network analyzer is handheld and includes a 2.8 in touch screen and 400mAh battery for 2 hours of offline use. For longer measurements, connect an external power supply or make a larger battery version. TX or RX method can measure the complete S11 and S21 parameters. You need to change the transceiver port wiring manually to get S12 and S22. specification:Item Type: Vector Network Analyzer Material: PCB, Metal Display: 2.8 Inch TFT (320 x 240) Measurement Range: 50KHz-300MHz RF Output: -13dbm (Maximum -9dbm) Port SWR:
