The battery used is a 3Ah LiPo battery, which is plenty as the current consumption is at 400mA maximum. The pictures below are the back side of the LCD boards. Here we have the two stacked boards dissembled. You will also learn a lot! It's a wonderful, amazing device. Unlike the other NanoVNAs we had done teardown with, the SAA-2 utilizes a two-board design with two PCBs stacked together. For the binding posts adapter, you'll also want a 50 ohm resistor for doing calibration.Īnd whichever you choose will bring you a lot of capability and probably a lot of fun. The binding posts adapter was nice for testing toroid impedance matching transformers I was making, for use with high-impedance antennas. ![]() Today we take a look at the NanoVNA SAA-2N, this partic. I've added male & female adapters for BNC, UHF, and F connectors, plus a BNC-binding posts/banana jacks connector that's good for testing wire-lead components like toroid coils. Lets take a look at this SAA2 and also the SAA2N versions of the NanoVNA and compare them to earlier models. One of the best tools for a Ham Radio Operator is a NanoVNA, these come in many different varieties. A small case with dividers inside is also very handy for storing and organizing the adapters. Whichever you choose, be sure to also order connector adapters that you will need. ![]() All models seem to have very good PC software support. ![]() The -H is much smaller and lighter, easily fits in a shirt pocket, but is harder to read and VERY hard to read in bright, outdoor light. Now, he announced another package, a NanoVNA V2 (3GHz) with 4 inch. Hugen, a pioneer in the area brought earlier the NanoVNA-H and NanoVNA-H4 and TinySA spectrum analyzer in quality packaging with cases, cables, bags, etc, complete products. I really like my -F, and also have a -H that was my introduction to NanoVNAs. In this year, 2020, we have seen the explosion of the NanoVNA devices, creazy cheap VNAs for the masses. I believe it's also a bit more expensive, and uses a different firmware version (I think). ![]() The SAA2 would be preferable if you need measurements above 1.5 GHz and/or need to use type N co-ax connectors. There are several programs for Windows (including 10), and one for Android. Also I am not sure if either of the software programs will run on Windows 10?
