For NANO VNA 400mAh Battery Touch Screen NanoVNA-H4 Network Vector Antenna Analyzer

Features: brand new high quality Nanovna 50KHz-900MHz Vector Network Analyzer UHF VHF VNA HF Antenna Analyzer [50kHz-900MHz wide frequency range]: si5351 direct output provides better than 70dB dynamics in 50k-300MHz frequency band, extended 300M-600MHz frequency band provides better than 60dB dynamics, 600M-900M frequency band is better than 50dB dynamics. 【Improved Frequency Algorithm】: The standing wave meter can use the odd harmonic extension of si5351 to support measurement frequencies up to 900MHz. It allows you to directly measure S11/ 1 parameters. To get S12/ 2 curves, manually swap the TX/RX ports. 【USB Antenna Analyzer】: HF VHF UHF VNA Antenna Analyzer provides complete vector network measurement capabilities. 2.8 inch LCD TFT digital display, built-in 400mAh battery ensures more than 2 hours working time. Easily charge and control the NanoVNA on a PC via a USB cable. 【Small and Portable, Easy to Use】: The Open Hardware NanoVNA Bundle is designed to provide hobbyists with RF gadgets but useful instruments. The upper computer control software can export Touchstone (snp) files, which can be used in various radio design and simulation software. 【Perfect DIY Tool】: No need for a metal shielding case, you can directly open the machine to view the circuit structure. Recommended for learning principles and use at lower frequencies. for clients who study can DIY, miniature and handheld.
