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.

A great product! Very nice and neat case, small size, is very accurate in its measurements (I have multiple calibrated meters and this one is just as accurate) and has all the functions you need from a multimeter plus the large screen ability makes it very versatile.
Both my colleagues saw me using a multimeter, consulted me about it, they both bought one, and each was very happy with his choice. I recommend it unreservedly.

Reviewed in the United States on April 24, 2023
These have a wide useable range from 0.01 MHz to 1500 MHz and like any other Nano VNA they're limited by how many data points they can spit out over a given range, think of that wide range like a huge "cake" that can only be divided into say 10 equal portions (data points). But say you want to test a 70cm/440 MHz antenna? Select a smaller area of the "cake" say from 420-450 MHz where the antenna is actually useable or an even narrower range first if you want better test results and the Nano VNA will still divide that smaller portion into 10 equal parts giving you more accurate data results.
I'd also recommend getting a fine tip touch screen stylus to make navigating the menus easier, that can be a bit frustrating if you have fat fingers.
Top reviews from other countries
Once you've calibrated with the open, short & load plugs supplied, the accuracy is surprisingly good for an inexpensive meter.
Even the calibration plugs return the same results as significantly more expensive ones.
I've tried standard SWR measurements, Smith Chart for measuring inductance & capacitance and the TDR function for measuring the length of a piece of coax. The Velocity Ratio I used was a bit of a guess - but the result was within 10cm over 100m.
