Review: The NanoVna SAA-2N VNA is excellent value. - My NanoVna SAA-2N VNA gives a top-notch performance, rivaling other analyzers at a fraction of the price. The 4-inch LCD screen is easy on the eyes. The only minus I've found is that you must manually save the calibration data for each frequency band, which is not a biggy if you work mainly in one or a portion of a band. Recalling calibration data is as simple as pressing a button on the touch screen, and speaking of which, the touch sensitivity is perfect. I opted for the N-type connectors with better longevity than (tiny) SMA. SMA-to-N-type adapters are easy to use. The unit is in a strong metal housing and has an easy-to-use zipper-style protective storage/carry case. Highly recommended for ham radio work and experimentation.
Review: Well worth the extra money - I replaced one of the smaller NanoVNAs with this. I considered those $50 VNAs to be useless junk. I was very pleasantly surprised at the quality and functionality of this one. The connectors and cables are lab grade and very high quality. I had this up and running RL and IL tests in under 5 minutes (including the initial calibrations). It's not a $50,000 network analyzer, but its performance really isn't that far off for 99% of what I do... and for the money? Yes, this could be used for antenna work up on the tower, but modern antenna analyzers (like those made by RigExpert for example) are much more user-friendly than a VNA for antenna work. This is intended to be a bench top analyzer and it performs that function very well. The S11 TX port is essentially an analyzer that does pretty much the same functions as a hand-held antenna analyzer, but the addition of the receive port brings in a new dimension: this can also do RF insertion loss measurements. This was a much needed function on my test bench and allows me to do filter work. Don't waste your money on the $50 VNAs. Buy this one.

## Features

- Upgraded NanoVNA SAA-2N V2.2 Version: Not only testing standing wave impedance of the antenna, can also 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.4.0 inch touch screen make it easier for you to read data and test
- Calibration :The SAA-2N/NanoVNA_V2.2 does not load the initial calibration data at startup, and does not automatically interpolate the calibration data after the user changes the frequency, and must recalibrate or recall the calibration data (previously saved data) after each startup and frequency change. Please read the user manual carefully before use to avoid damaging the device
- Improved Frequency Range:transmission Mearsure S21: 70dB(50KHz-1.5GHz), 60dB(1.5GHz-3GHz). Reflection Measure S11: -50dB(50KHz-1.5GHz), -40dB(1.5GHz-3GHz); Antenna Analyzer: 1.005(50KHz - 1.5GHz), 1.02(1.5GHz-3GHz)
- Improved Performance: High stability, high sensitivity, high precision, improved performance.Made of high-quality aluminum protective case, strong practicability and long service life.Bulit-in 3000mAh rechargeable battery,USB powered
- What You Can Get: 1x NanoVNA SAA-2N VNA, 1x Micro USB Data Cable,2x 500mm N-type Male to Male RG142-PUR RF Cable,1x N-type Male Calibration Kit-OPEN,1x N-type Male Calibration Kit-SHORT,1x N-type Male Calibration Kit-LOAD,1x N-type Female to Female Connector,1x EVA Storage Bag, 1x Touching Screen Pen and Lanyard,1x Testboard ,1x Accessories Kit, 2x 12 hours services

### ⭐⭐⭐⭐ Okay for the price, and it can connect to nanoVNA Apps.
*by K***H on June 24, 2025*

Connects well to my computer, and is compatible with multiple nanoVNA apps (nanoVNA App, nanoVNA Saver, VNA QT all worked). That's great, I've tried a couple different models from other brands that were problematic. Unfortunately, the unit I received was missing items (no cal set(s), missing a cable), which the seller said they're sending me. However, it's coming from overseas, so it will be a while before I can properly use this. I tried calibrating with adapters and a set from another VNA, but the results weren't great. The screen is smaller than I would prefer, but it looks better than the pictures in the ad. I wish this model was updated with a USB-C connector instead of the old micro USB port. The photo in the ad is weird. It looks like it might come with 2 cal sets, but I got 0. One cal set would be enough to get started. I'm not sure what the SMA looking pieces are supposed to be in the photo if it's not a secondary cal set. Update: The seller took care of the missing stuff, and it's all good now. Good seller, good product.
