BFKK NanoVNA SAA-2N V2.2 Network Antenna Analyzer 50KHz-3GHz

SKU CH-G7Z0-Z9CQ7

Measures antenna SWR, S-parameters, cable loss and phase from 50 kHz to 3 GHz with 70 dB dynamic range to 1.5 GHz

  • Measures S-parameters up to 3 GHz for antenna and filter analysis
  • 70 dB dynamic range to 1.5 GHz and 60 dB to 3 GHz for transmission tests
  • Reflection accuracy better than 1.005 to 1.5 GHz and 1.02 to 3 GHz for reliable VSWR data
  • PC control via VNA-QT on Linux, Windows 7+ and Mac OS planned for remote operation
  • Open-source LGPL firmware from OwOComm enables updates and community development

Purpose & Audience

The BFKK NanoVNA SAA-2N V2.2 is a portable vector network analyser covering 50 kHz to 3 GHz. It suits radio amateurs, RF engineers and students who need S-parameter, VSWR, phase, delay and cable-loss measurements in the field or on the bench.

Setup Checklist

Verify that your PC runs Windows 7 or later, Linux, or macOS for VNA-QT and NanoVNA-Saver control software. Ensure a USB connection is available and note that calibration data is not loaded at startup; a full recalibration or manual recall is required after every power cycle or frequency change.

Upgrade Path

Replaces basic SWR meters and scalar analysers that only show reflection magnitude. The jump is worthwhile when you need calibrated S11 and S21 data up to 3 GHz with 70 dB dynamic range below 1.5 GHz and 60 dB above, plus phase, delay and Time Domain reflectometry functions.

Questions about this item

What comes in the box and do I need to buy cables or a battery separately?

The analyzer ships with the main unit and a USB cable for charging and PC control. No RF cables or external battery are included; you will need to supply your own SMA test leads and a portable power bank if you plan to operate away from mains power.

Should I choose the 1.5 GHz or 3 GHz version for duplexer and filter testing?

There is only one hardware version covering 50 kHz to 3 GHz. Transmission dynamic range is 70 dB up to 1.5 GHz and 60 dB from 1.5 GHz to 3 GHz, while reflection dynamic range is -50 dB and -40 dB over the same split.

What does the 70 dB transmission figure mean when I measure a filter on the bench?

It is the maximum measurable insertion-loss dynamic range. Below 1.5 GHz you can resolve up to 70 dB of attenuation; above 1.5 GHz the limit drops to 60 dB, so very deep filter notches may hit the noise floor earlier.
