NanoVNA-F V3 Vector Network Analyzer
The NanoVNA-F V3 is a portable two-port vector network analyzer for antenna, filter, cable and RF network evaluation from 1 MHz to 6.3 GHz. Its 4.3-inch touch display supports field adjustment and on-device review without requiring a computer for routine measurements.
RF measurements
- Frequency range: 1 MHz to 6.3 GHz
- Two-port measurement for reflection and transmission analysis
- Supports common traces including SWR, return loss, impedance, phase and gain/loss
- Useful for antennas, filters, attenuators, cables and matching networks
Calibration and workflow
Perform open, short, load and through calibration at the intended reference plane before measuring. Recalibrate after changing the frequency span, test cables, adapters or fixture arrangement when measurement accuracy matters.
Portable operation
The unit combines a 4.3-inch display with a rechargeable 4500 mAh battery for bench or field use. USB connectivity supports charging and computer-assisted analysis where compatible software is used.
RF safety: Do not connect an active transmitter or signal source that exceeds the analyzer input limit. Confirm the device under test is de-energized or suitably isolated before connection.
