AURSINCNanoVNA SAA-2N V2.2 Vector Network Analyzer Calibration Kits, N-Type Male Short & Load & Open & Female to Female Connector | 4 pcs/Set

Just arrived today and I am totally blown away by this little compact 3GHz capable VNA for $130 bucks. I am nearly giddy with amazement, because not only is the construction of the product (full metal case) solid built, but hardware is really quite capable. As anyone who has previously purchased the NanoVNA series knows, its very functional for hobby and minor field work. This unit, the SAA-2N V2.2 is the latest in the NanoVNA series which now includes 'N' type RF connections instead of SMA. Most engineers and HAM enthusiasts will appreciate that when you need to connect to antennas outside, or test receiver LNA's and downstream equipment, you likely need to use N-type connections. Noting that it is totally possible to use N-to-SMA adapters for the earlier models, the problem lies in the fact that when you attach a heavy N-type cable to a same fragile SMA adapter, you run the risk of snapping it in two, but not so with this unit. The SAA-2N V2.2 has the same good RF performance for S-parameter measurements as previous models, so I won't cover that in this review. Having the screen now at a pleasant 4 inches is very helpful compared to the earlier 2.7", and 3.2" versions. The specs have conflict when it comes to battery capacity, in the graphic images is a comparison that says it has 3000mA/Hr but down in the text area of the spec it states 1950mA. I will have to report back to really see which is correct. I own a very nice HP8753C vector network analyzer along with several calibration kits. I ran some tests using the HP85032B cal kit on my VNA and then testing each of the three hardware cal adapters that came with the SAA-2N V2.2 . The Short and Open have virtually no difference and the RF 50ohm Load held better than -30dB return loss at 3GHz, which is really not bad. That is a VSWR: of 1.065. Using a 10dB attenuator on S11 port, yielded a near perfect -19.96dB return loss. The two N-Type to N-Type 20.5" long cables are pretty good, and able to maintain a -23dB return loss out to 3GHz, which is better than Port 2 can perform at (-13dB RL).I really am impressed at what it can do and all that is included for the price. I now can have a portable VNA virtually anywhere I go. And if you need a hardcopy of your measurements, you can download the free PC software from GITHUB which will allow the VNA to output data via the USB port to the computer and then you can save it in S2P or CSV for later. (You have to make the measurement while using the software, and you can't save it on the instrument and then later print it via the PC.)Fantastic piece of gear for the money!

This has become an Absolutely Indispensable Tool for building and tuning antenna! I like the much more durable N-Type connectors as opposed to the delicate SMA types found on cheaper VNAs. This comes with all you need to make connections to PL-259 and Type-N RF connectors. Seems very accurate, and very durable in its metal chassis. The price is reasonable for what you get. Buy this, you’ll appreciate the quality.

Out of box experience overall: Not bad!Couple of minor negatives to get out of the way: The case is steel. Consequently it is a lot heavier than it needs to be, and subject to rust. Would have preferred aluminum for obvious reasons. The screening on the case is essentially unreadable. Good news is there are few things to label. RF N Port 0 is the one closest to a protruding tab. Menu open is center button, other buttons are up / dn navigate, or just use the touch screen. Finger or included stylus. Also a USB:C would be preferred I'm guessing for many, but the USB mini cables are plentiful plus it is supplied with one. No on-screen batt voltage indication, but the 3 LEDs on the back that are grouped together show a 100/66/33 % power left indication and seem accurate enough. While charging each LED will sequentially blink to show charging status until all are solid.illumination. Seems to charge quickly from standard phone charger. (2 to 3 hrs)YouTube is your friend for quick start. They are all very similar in operation.Some Big Pros I see with this unit:N connectors! I don't really trust flimsy SMAs for long-term use like most of them have.You can Calibrate for a particular freq range and save to a slot. Comes with calibration slugs. Slot 0 is recalled at power up. Config settings such as screen rotate are also recalled at startup. This makes this unit very useable for frequent repeated antenna tests.You can turn it on an test an swr sweep or other tests in seconds! Easy to recall other calibrations for other ranges/antennas from other slots. 10 slots. Attached photo tests a commercial airband antenna and to my surprise it was right in spec. No more guessing about antennas whether commercially purchased or home built! Up to 201 scanning points per selected freq range compared to half that for most nanovna units. The plots seems smooth without a lot of noise.Nice bright screen! Case holds all accessories, though it is a tight fit. You should be able to fit in a couple extra adapters such as UHF or SMA but that's about it. Haven't used PC software yet. Provides more capability, but the beauty of this is quick accurate tests in the field just stand-alone. Recommending for the moment.

This unit is solidly built, has newer brighter screen, GREAT for amateur radio use checking out antenna's and coax feed lines!! plus many other applications as well!!

No olviden pedir elnkit complementario

En general buen equipo, buena relacion costo calidad, lo recomiendo, muy robusta su construcción.
