Handheld vector network analyzer with 4.3 inch touch screen and aluminium housing

BFKK

BFKK NanoVNA-F V2 Vector Network Analyzer 50kHz-3GHz 4.3 inch Touch Screen 5000mAh Battery

SKU CH-BZDQ-734RB

Handheld vector network analyser covering 50 kHz to 3 GHz with a 4.3 inch touch screen and 5000 mAh battery

  • Wide frequency coverage from 50 kHz to 3 GHz
  • Large 4.3 inch IPS touch screen readable in bright light
  • 5000 mAh battery gives long field use and can charge phones
  • Aluminium housing shields SMA port from external interference
  • Dynamic range of 40 dB at 600 MHz to 1 GHz ensures accurate S11 measurements

Handheld VNA with 4.3 inch Touch Screen

The BFKK NanoVNA-F V2 is a handheld vector network analyzer covering 50 kHz to 3 GHz. It uses a 4.3 inch IPS TFT LCD touch screen with 800x480 resolution and adjustable brightness for clear outdoor visibility. The aluminium housing shields the SMA connector and reduces external electromagnetic interference. It is built for field engineers and hobbyists who need portable S-parameter, SWR, phase, group delay and Smith chart measurements.

5000 mAh Battery and USB Power Output

The upgraded 5000 mAh 3.7 V battery provides longer standby time and charges at 2 A for shorter charging cycles. When the analyzer is not in use, the extended USB interface allows the unit to function as a mobile power source for charging Android or Apple phones. Firmware upgrades are performed via a virtual USB drive connection, and the interface supports Chinese and English menu switching.

Measurement Range and Dynamic Limits

The analyzer measures from 50 kHz up to 3 GHz, with an official firmware option to expand the lower limit to 10 kHz and the upper limit to 1.5 GHz. Harmonic expansion of the SI5351 clock output enables measurements to 1000 MHz. Between 600 MHz and 1 GHz the S11 dynamic range reaches 40 dB, corresponding to a standing wave ratio below 1.02. Above 1 GHz the dynamic range decreases, limiting accuracy for high-frequency S11 work.
