Review: After two faulty units the third works perfectly. - The problem I faced was related to the battery in the device. The first two had bad batteries that were bulged. Likely due to the way they were stored, so I cannot say for certain that the problem was related to the seller or the desertcart warehouse where they're held. After a back and forth over a few days and returns, this device is exactly as expected and works pretty well. Sometime soon I'll update with a comparison of the data obtained from this model vs. the Keysight and Agielent VNAs I use at the University.
Review: This is a revolutionary tool for Armature radio - The larger size is well worth the added price. The instrument case is a handy addition. The flow chart is a helpful addition. The inter connection screw in is a pressed part not machined we are used to with American parts. The increased frequency spectrum works on harmonics that limits the dynamic amplitude range of of the extended frequency. The enclosed case for the instrument is a welcome feature. The board with the experiments is a easy way to learn how to use the instrument. Proper documentation is a must. I wish it was made in the United States we under stand quality control, technical support and how to document what we design.

## Features

- Seesii UPGRADED NANOVNA ANALYZER: SeeSii Vector Network Analyzer is developed by Hugen.With 50kHz-6.3GHz measure range, 4.0 inch 480 x 320 touchscreen,mini and portable design.In order to minimize power consumption and size, the analyzer uses only one mixer, which allows S11 and S21 measurements through internal RF switching and can allows TDR and DTF measurements through IFFT calculations.
- 50kHz-6.3GHz FREQUENCY RANG: Compared to the previous NanoVNAs (10KHz-1.5/3GHz), SeeSii antenna analyzer has 50KHz-6.3GHz ultra-wide measuring frequency range with precision and accuration improved. Not only testing standing wave impedance of the antenna, but also can debug the duplexer, the insertion loss of the filter, the isolation and testing the attenuation of the cable, shorten the coefficient, the phase, the amplification of the antenna amplifier.
- BUILT-IN MICRO-SD PORT & TIME DISPLAY: The lastest antenna analyzer with MicroSD card port,so you can save field test data or screens to a MicroSD card at any time,support up to 32GB memory card. (Not include in the pacakge).In addition, different from old version NanoVNAs, the date and time can be customized, which is convenient for you to further record and save data.
- ULTRA-LONG BATTERY LIFE & PC CONTROL:The upgraded nano vna analyzer built-in 2000 3.7V rechargeable battery,with type-C charging cable,can be fully charged within 3 hours,no need to charge frequently. Above all, it supports PC control, compatible with Linux, Windows (7+), Mac OS (10.11+). Can export Touchstone (snp) files for various radio design and simulation software through PC software.
- WIDELY APPLICATION: This network vector analyzer is mini but powerful design.It can measure almost all ra-dio equipment:SWR/SMITH/SHORT WAVE/MF/HF/VHF/SSB/BALUN/TDR/DTF/LOGMAG/PHASE/DELAY/POLAR/LINEAR/REAL/IMAG/RESISTANCE/REACTANCE/Antenna/Filter/Duplexer, is capable of meeting common amateur radio and IoT applications, as well as emerging 5GHz testing, enabling the application of the latest 5.8GHz wifi and 5.8GHz image transmission.

## Questions & Answers

**Q: Is this useful for 1.575 ghz gps band?**
A: Do you think this is a receiver? It is not it's a Rf source coupled to a two port RF coupler with computing power to display data of a RF circuit. A spectrum analyzer is available to show wide bands of frequencies and their position in the Rf spectrum

**Q: What data can you get from the signal. Like let's say it's a 5G wifi signal, what will it tell you? Can it register the data sent on that signal?**
A: This device that looks at a complex electronic circuit such as a receiving antenna. (Beam). Give you information on return loss of the antenna. It can analyze a Rf amplifier give you gain frequency response. It displays the result in a frequency vs Db graph and complex analyses in a smith chart. You can display four pages at a time. You can download a program to display the small screen on a PC. At a fraction of the price of a bench top instrument. You can put it in your pocket Its battery operated. You can send the display from your PC.

**Q: How far does this measure in meters or feet?**
A: From my usage it seems accurate as far as a meter. It's the only coax line I have tested since I am building an antenna from semirigid cable. I've seen others use this to measure lengths up to 50 meters, but I would think it will work to lengths higher than that.

**Q: Does it support scpi commands? if so, then how many? do you have a list of commands? can i get raw iq data from it? thank you**
A: There are several FREE computer programs that display smith charts. As to. I have only used one program. Al the commands are explained. People are adding new programs all the time it is hard to keep up with what amiable currently.

### ⭐⭐⭐⭐⭐ Great unit works well
*by S***T on September 4, 2023*

Great little item, does what it claims, changing to high mhz bands is difficult.
