Considering its costs and size, this VNA is particularly efficient and can easily cover all needs of home-made DIY projects of amateur radio operators and fans of RF and sub-microwave experimenters, looking for a portable, yet satisfactorily accurate for its category VNA.
I would say that any serious individual working on radios, antennas and RF components/circuits, etc should stock this. Product is also supported by an active forum, regular firmware upgrades, fixes and improvements. You can plot up to 4 traces simultaneously, which is useful for more complex measurements (either S11 or S21). Battery lasts for several hours (I've set screen intensity to 10% - this helps to conserve battery) and there is also PC connectivity over USB-C cable, which allows you to display measurements in real-time in your PC display, etc.
Note the VNA screen is of resistive-type, and not capacitive, this makes pressing of buttons a bit 'weird' at the beginning, compared to a mobile phone screen, as there is a soft thin film on top of the LCD screen which bends inwards upon pressing. Eventually you will get used and it won't be a great deal.
LiteVNA 64 vector network analyser
Details
The LiteVNA is a portable 50 kHz - 6.3 GHz vector network analyzer which design is based on the
NanoVNA and SAA2. This vna is designed to measure equipment reflection and transmission coefficients without the need for a large analyzer.
The LiteVNA uses one mixer which enables S11 and S21 measurements through RF switching and TDR/DTF measurements through
IFFT calculations.
The analyser has a 3.95" touch-screen display that can show the measurements in 10-1001 data points. Furthermore,
the analyser has a built-in 2000 mAh battery and can be connected to an android phone or PC. Connecting
to a phone or PC allows for controlling the analyser and displaying the measurements.
