NanoVNA is open hardware with many visually similar clones; this record selects Nooelec SKU 100831 and Fab.to.Lab product code NE-NanoVNA-H-4 for provenance, not a generic H4 or 100833 accessory bundle. Confirm the box label, firmware/source route, sealed calibration standards, invoice, battery condition and warranty administrator. Perform a fresh SOLT calibration at the measurement plane whenever the frequency span, cables or fixtures change. Dynamic range and trace noise are limited compared with calibrated laboratory VNAs, especially toward the upper range; use averaging/smoothing cautiously and verify critical results with known standards.
Never connect a powered transmitter or unknown high-energy RF source directly to the VNA; the test ports are low-level measurement ports and can be damaged. Observe ESD precautions at SMA connectors, use attenuators or DC blocks where required and remain within published input limits. The lithium battery is regulated for transport and should not be charged unattended or used if swollen/damaged. This is not an accredited metrology instrument; document calibration method and uncertainty for professional or compliance work.
