GOOZEEZOO 2023 the Newest LiteVNA 50kHz to 6.3GHz Vector Network Analyzer
Combination and Improvement
- LiteVNA Antenna Analyzer also brings in a swifter sweeping rate (>550 points/s) and more sweeping points(adjustable 10-1001 points on device, adjustable 1-1024 points thru USB).
- Combining the easy operating system of the former NanoVNA, LiteVNA now can be conveniently used for the measurement tool at site.
LiteVNA Performance Upgraded:
- In order to minimize the power consumption and the size, the LiteVNA antenna analyzer is only equipped with one mixer;
- Through switching the internal RF, the portable VNA measures S11 and S21 parameters, plus measuring TDR and DTF through IFFT calculations.
- Note: Random Loud Noises might occur when connecting to the external power, due to the resonance between the external power frequency and the switch power

Measured an HP 30 db attenuator used to calibrate power meters (very precise but only valid at 50MHZ)Attenuation was exactly 30 db.Had success with many other components.There is a test board for the nanoVNA (sold separately) with that test board, there is an inductor.for some low frequencies (R+ jX in Smith chart) I was getting negative values of R, yes -R.This is simply not possible R is ALWAYS positive.The firmware might need to be updated, because it appears that it's doing "pure math" computationswithout ANY regards to physical reality.Yes, I can do math on complex numbers and get a real part that is negative. But this is not just a mathproblem. The physical realities do NOT allow the resistance to be negative.For test frequencies below 875KHZ, R was negative. (Very small surface mount inductor )

This little thing is great! After a short learning curve (watch a Youtube video) you can be tuning an antenna in no time. I have an OCFD that has been through several ice storms, stretched longer than it should be.The Nanovna allows you to see small changes in your SWR sweep, I can fold back as little as 4' on one end of a 135' dipole and see the change in SWR and band coverage. I was able to lower the SWR overall while tuning the low SWR to the part of the bands I use most, the Nanovna saved my antenna from the scrap pile. This is the best bang for your buck in your shack, feed your antenna not your coax!

There are so many video on the use of this device it seemed like a great fit. The pc based software is super easy to use as well as the touch screen. I got two sets of calibration parts, overall I think it represents a good value.

This is a wonderful product for the price I paid and function it will doLittle bit of a learning curve nothing some YouTube videos didn't take care of I'd recommend this to anyone

I'm happy with the results I'm getting and for the price I have no real complaints. Using for ham and GMRS radio, but also has other measurement application for me (I'm and electrical engineer). The touch screen is the largest detractor from a 5-star review. Don't lose the stylus, it's not easily operable without it. (The screen is an out of date resistive type, and not a very good one at that.) Then again, it doesn't cost $300. The instruction sheet is woefully inadequate, basically a menu tree and nothing else. They should at least have a link to complete online instructions written in good English. You are doomed to watch a dozen hours of YouTube to learn how to use it. Storing and retrieving calibrations is not intuitive and will take more practice than I have done so far. If I get deeper into it, I'll have to write my own operator's manual for it to keep as a reference. The included adapters work for SMA connections, but you will need to order a bevy of other adapters for anything other than basic use.

This item works as it should. Case could be made out of more durable plastic, but you get what you pay for and I opted for the lower price Nanovna. Works great for what I need to do as far as my amateur radio antennas. I did get the nanovna test board and demo kit which was a much needed and helpful item to go with the nanovna. Compared to the higher end antenna analyzers, this one may not be as accurate, it will be close enough for me to save hundreds of dollars over one of the name brand analyzers.
