Check the listing for details. NanoVNA 50KHz-2GHz Vector Network Analyzer for MF HF VHF UHF Antenna 2.8". Condition: New. Listed at 40.85 USD. Description50KHz-900MHz NanoVNA Vector Network Analyzer for MF HF VHF UHF Antenna 2.8" Touch Screen W/O Shell Description: We have redesigned its PCB board. Designed with simple but practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software. Its improved frequency algorithm can support the measurement frequency of 900MHz with the odd harmonic extension of si5351. Designed with a metal shield to reduce external interference and improve measurement accuracy, si5351 directly outputs frequency of 50K-300MHz with dynamics better than 70dB. Its expanded 300M-600MHz band can provide dynamics better than 50dB, and 600M-900M band with dynamics better than 40dB. It is a DIY vector network analyzer. It features a 2.8-inch touch screen, 400mAh electricity for off-line application in 2 hours. If you want to prolong the testing time, you can connect it to an extra power bank, or contact us for larger capacity. As for testing via TX/RX, you can get full set of parameters of S11 and S21. What you have to do is to replace the connection cables in the receiving and transmitting ports.
