Upgraded NanoVNA-H4 Vector Network Analyzer, Latest V4.3 10KHz-1.5GHz HF VHF UHF 4 S Parameters, Voltage Standing Wave Ratio, Phase, Delay, Smith Chart Touchscreen Antenna Analyzer

• The latest upgraded version of the NanoVNA-H4 is equipped with a 4-inch LCD touch screen and a 1950 mAh battery rechargeable or USB powered
• Improved Frequency Algorithm: Vector network analyzer uses si5351 odd harmonic expansion and supports measuring frequencies up to 1.5 GHz. The 50K-300MHz frequency band with a direct output of si5351 has a dynamic range of more than 70dB, and the extended 300M-900MHz band provides a dynamic range of over 60dB and the 900M-1.5GHz band provides a dynamic range of greater than 40dB
• SMALL PORTABLE & POWERFUL This antenna analyzer is a DIY product that provides perfect vector network measurement capabilities, small and handheld. The main function of the default firmware is used to measure the antenna performance. The TX/RX method can measure the full S11 and S21 parameters (need to change the wiring for the transceiver port manually)
• PC Connection: Using the PC software NanoVNASaver, you can connect it with NanoVNA, extracts data and store it to your computer or touchstone files. You can also export touchstone (snp) files
• Improved Precision Metal Shield reduces external interference and improves measurement accuracy
