This is a fun board to play with. You should purchase it immediately if you are going to buy a Nanovna. You won’t regret it.Photo shows a sweep of circuit 6 (10.7mhz band pass filter) on a Nanovna H4, running V1.2.40.

As it stands it appears to have a quality PCB. With good soldering technique it should be good for years of experimenting with RF circuits.

I've used this with my LiteVNA and it seems to be accurate. I get the expected results from all my tests with it. The little Hirose connectors are always a little hard to deal with, no matter what product they're installed on, but they're good quality and they're necessary in order to be able to fit all the required connectors on this board. I recommend this test board.

If you are new to a VNA, this board is a must. In my case I had to quickly learn RF concepts to complete a project and this PCB allowed me to learn the NanoVNA and all its functions quickly and easily. As I am not a expert, when I do need something, this is a quick way to refresh my memory.

Works perfectly. But if you have trouble dealing with tiny snaps, you will find it difficult to connect the test leads.

When you first take a look at the PCB, the quality looks good soldering of the components look good. I have not tested each circuits and see if they perform as described, when I do, I will comeback and update this review. With regards to the connections to each circuits, I believe that the connections have 30 or more use before they become loose and unusable. I will give it a for for now.

This would ideally be shipped with each NanoVNA that is sold! It is a terrific way to get to know how the equipment works, to calibrate it, and to teach other people how to use the device. Be careful with the delicate connectors at the end of the cables (provided) where they plug onto the board. (Push/pull on the connectors, not the cables, just like any cable assembly you already have.) This board itself is very solid and I assume quite rugged, and is fabricated using modern best practices for GHz planar construction, with no moving parts. Also a cheat sheet included on the back of the circuit board.

Much like the NanoVNA this is supposed to be paired with, this is pretty good for the price. The board I received had all the functions working in a general sense, but the accuracy was lacking.The 400MHz LPF had a -6dB drop at 400MHz, while the 500MHz HPF had a -2dB drop at 500MHz. Both of those should be -3dB. The band-pass and band-stop filters came in pretty close to their specified frequencies, but they were also much lower in frequency than the HPF and LPF.The various impedances were again, close to the intended value, but not quite exactly as drawn.Overall, I'd recommend having this as a quick reference for the NanoVNA, however with the big caveat that you need to keep in mind that it's only "close enough". For any super accurate RF circuits, you'll have you make your own, or spend more money.
