NanoVNA-H4 10Khz-1.5GHz Portable Vector Network Analyzer VNA for MF/HF/VHF/UHF/SHF

The NanoVNA-H4 is no ordinary instrument. This DIY marvel offers professional-grade vector network measurement capabilities in a compact, handheld form factor. Imagine a powerful tool that fits in your palm, boasting a vivid 4-inch LCD touchscreen display. Not only is it portable, but its built-in 1950mAh battery keeps you going, or you can utilize USB power for extended use.

Under the hood, the NanoVNA-H4 leverages an ingenious frequency algorithm. By harnessing the odd harmonic extension of the Si5351 chip, it extends measurement frequency up to a remarkable 1.5GHz. Here's the breakdown:

• 50kHz-300MHz: the Si5351's direct output delivers an impressive dynamic range exceeding 70dB.
• 300MHz-900MHz: the extended band maintains a solid dynamic range above 60dB.
• 900MHz-1.5GHz: even at higher frequencies, the NanoVNA-H4 provides a respectable dynamic range exceeding 40dB.

The default firmware prioritizes antenna performance analysis. Utilizing the TX/RX method, it effortlessly measures critical S11 and S21 parameters. For those requiring S12 and S22 measurements, a simple manual reconfiguration of the transceiver port wiring unlocks this additional capability.

Taking your analysis further? Partner the NanoVNA-H4 with PC software like NanoVNASaver. This software bridges the gap, allowing you to extract data from your NanoVNA and display it on your computer for in-depth analysis. But that's not all! NanoVNASaver facilitates saving this valuable data in Touchstone (snp) file format. These industry-standard files can be seamlessly imported into various radio design and simulation software, empowering you to refine your creations.

The commitment to accuracy extends beyond software. The NanoVNA-H4 features a robust metal shield that effectively minimizes external interference, ensuring your measurements remain precise and reliable.
