About this item

  • Unit is designed to fit for Original Equipment, form and function Simple and practical PC control software, you can export Touchstone (snp) files for various radio design and simulation software through PC software.
  • The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The 50KHz-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics
  • The extended 300M-600MHz band provides better than 60dB of dynamics, and the 600M-900M band is better than 50dB of dynamics.
  • Requirements accomplished by leveraging Spectra Premium's OE engine management systems design expertise.Platinum connector threads reduce the number of connection points for faster reaction to change.Ceramic-built printed circuit boards are protected by silica gel, providing superior resistance to temperature changes and vehicle vibrations.
  • This is a DIY product that provides perfect vector network measurement capabilities in the size of a credit card. It includes a 2.8-inch touch screen and 500mAh battery, which can be used offline for 2 hours. For longer measurement, please connect external power supply or contact me to make a larger battery version. The TX/RX method can measure the complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring.

2.8 Inch Touch Screen

Touch Operation:

You can move the mark point or perform a menu operation via your hand directly or multi-functional switch.

Wheel Operation:

You could also rotate the wheel to operate it. Pressing is confirm. Left/Right rotation to move the selection.

SWR & Smith Chart

The SWR readings are accurate for tuning antennas from 50kHz to 900MHz. Smith chart will help you to determine reactance and resistance for an antenna.

Based on odd harmonic extension of si5351, NanoVNA will transmit the signal with maximum efficiency and minimum distortion. Frequency Accuracy: 0.5PPM.

Built-in 650mA-h Battery

You can connect the vector network analyzer to your PC for a large screen display with a USB-C cable. The working time is above 2 hours.

A must have for HAM radio operator

A must have for HAM radio operator
This is a must have for any amateur radio operator. I was contemplating buying an SWR and antenna analyzer and the costs for that equipment from traditional outlets could be quite expensive. This does fit the bill for my needs and don’t have to buy multiple pieces of equipment to do it. It is a little bit of a learning curve, but YouTube is your friend.
