The original 4GHz second generation NanoVNA vector network analyzer, supplied by the team who designed it: nanorfe.com. This is the genuine nanoVNA, not a clone, and performs substantially better than the units you get on Amazon & eBay (take a look at the comparison below!)

We are an official distributor for nanoRFE in the UK, and we use them in our lab every day. They're fantastic devices. Stock is held in the UK for next day delivery!

The V2 Plus4 is the latest hardware version with improved shielding, 4" display, 90dB dynamic range, and 4x the sweep speed of other NanoVNAs.

Features

  • Latest original hardware - supported by all official software and firmware updates
  • 4 inch display
  • 50kHz - 4GHz frequency range
  • Low temperature drift - automatic internal calibration corrects for drift errors
  • High dynamic range (90dB), can measure duplexers (see comparisons and specifications below)
  • Real-time sweep - shows results as sweep progresses, more responsive than other versions
  • Faster update rate than other low cost VNAs (0.25s for V2 Plus4, 0.16s for V2 Plus4 Pro, see specifications below)
  • >1024 max sweep points (with NanoVNA-QT software); more points (up to 65535) are possible depending on the performance of your PC.
  • S parameter export
  • Custom calibration kit parameters (with NanoVNA-QT software)
  • Can be used standalone or with PC.
  • Supported by latest official firmware, with features:
    • TDR (time domain reflectometry/distance to fault) allows measuring cable length and discontinuities [example]
    • Can display smith chart, return loss, SWR, complex impedance, series equivalent (RC/RL), group delay, and more
    • Port length extension/electrical delay
    • Marker delta and marker search allows easily measuring minimums and maximums
    • Enhanced response calibration
    • Adjustable IF bandwidth, allows measuring crystals (V2 Plus4 Pro)
    • Adjustable ADF4350 output power
    • Firmware releases: https://nanorfe.com/nanovna-versions.html
  • Accepts standard flat-top 18650 lithium-ion battery, includes on-board protection and charging (note: after inserting a battery, connect USB power at least once to activate the battery management IC.)

Package includes

  • VNA (with aluminum enclosure; fully assembled)
  • 2 x 30cm SS405 phase stable cable
  • SOLT calibration kit SMA male
  • USB cable
  • Touchscreen stylus

Battery

Accepts standard 18650 lithium-ion battery. Includes USB charging.

Operation without a battery is also supported.

You can insert a standard 18650 flat-top unprotected 3.6V lithium-ion battery like the following:

The NanoVNA V2 Plus4 includes on-board battery protection and charging circuitry and can charge the battery from USB. See here for how to insert the battery.

After inserting the battery, you need to plug in USB power at least once to activate the battery management IC.
