I am very happy with this after having used it extensively for the last couple of weeks. A perk of my profession is that I get to use really expensive and capable test equipment at work but I wanted some of that capability for my hobby projects. That said I went into this purchase not expecting professional quality gear. My expectation was for hobby equipment and I feel like this product fulfills that expectation quite well.
There is plenty out on the web regarding what this does and does not do, so I won't rehash that here. I will say that there are many firmware available for this and some do different things, or do some of the same things differently. In any case, you will likely want to update the firmware on this or try one of the others. It is quite easy to do.
This particular unit came in a plastic case with a couple of cables, an SMA F to F barrel, and the terminations for calibration. A USB cable is also included along with a nice stylus, something that is absolutely a must for the operation of the touchscreen. Everything you need to get started is here except documentation. That's reasonable because any documentation will be specific to firmware and firmware changes often. So you'll get that yourself electronically and you'll likely want to watch some videos as well to get up to speed on the operation of it.
The included plastic case might be ok for some, but I recommend you put this into some more robust storage when not in use. At this price what you are getting is somewhat delicate and exposed. That's fine for a reasonably clean bench. I've even used it with care in the field. Just know that this isn't something you're going to casually throw in the tool bag, you're going to want to protect this.
So far I have enjoyed using this for a number of tasks including: sweep antennas, tune filters, tune antenna traps, measure inductors, measure capacitors, and so much experimentation with tuned circuits. Not only has it increased my productivity on my hobby bench, it's really helped me to learn some concepts and reinforce others. What a pleasure to be able to do that without worry because if I harm this thing in the process that's a whole lot different than playing around with my professional test equipment at work that costs tens of thousands of dollars.
In conclusion, this is a nice inexpensive bit of kit that produces reasonable results for the hobbyist. I am quite pleased with it.

Product Description
2022 AURSINC LibreVNA 100KHz-6GHz USB Based Full 2-port Vector Network Analyzer
Compatible with multi-PC Software and Vector Network Analyzer
LibreVNA PC software Control (Only 64-bit software is available for now)
LibreVNA Vector Network Analyzer Supports Full S-Parameters Measurements
LibreVNA Antenna Analyzer Troubleshooting:
If there was an error in the boot process, the "Booting" LED will bling an error code repeatedly:
Error Code - Meaning - Possible Solution
Code 1 - Failed to detect FLASH memor - Hardware failure, check soldering
Code 2 - Invalid FLASH content - Perform firmware update
Code 3 - Failed to configure FPGA - Check FPGA bitstream generator settings
Code 4 - Hardware initialization failed - Verify that FPGA bitstream and uC firmware are created from the same release
Specification for LibreVNA Network Analyzer
- Note 1: Above 3GHz, the performance decreases with increasing frequency, and the port isolation is only 50dB at 6GHz. Below 1MHz, the performance decreases with decreasing frequency, and the effective dynamic decreases to 70dB at 100kHz.
- Note 2: The use of higher accuracy calibrators allows for higher precision measurements.
- Note 3: The output power may decrease when the frequency is lower than 1MHz or higher than 3GHz.

Good Build of the nanoVna
There are hundreds of versions of this out there, this one is a good build and accurate if calibrated correctly. I use this mainly to check the swr on my antennas. I have also used it to trace the length of coax to a fault. It excelled at both of these functions. I use this all the time in my Ham shack when building new antennas. You must calibrate it when changing the stimulus settings. Also, it only keeps 100 calibration points so calibrate it only to the range you need for the best accuracy and always save to bank 0 as this is the bank it recalls when it is started up.The build on it is sturdy enough for bench use although I would not throw it in my field bag without keeping it in its plastic case. The case on this is open on the sides so using it in rain is a no go. The touch screen is good but better if you are using a stylus. For the price it’s the best antenna analyzer I have ever used. There is a bit of a learning curve with setting it up if you are used to a regular ham antenna analyzer but nothing that five minutes on YouTube won't cure.KI7FHU 73 all

There are many tutorials online but they do not give factory settings so if you change things before you know what you are doing you have to spend a considerable amount of time figuring what these settings were... Anyway all in all a good value for the money, can't wait to use for DIY antenna's to see how precise it is... 73.

Se requiere capacitación para entender los resultados pero es de mucha utilidad si vas a diseñar y contruir antenas de radio.
