AURSINCFilter Attenuator, RF Demo Kit NanoVNA RF Tester Board for NanoVNA-H NanoVNA-F Vector Network Analyzer Kits

The connectors are by design hard to putt on and take off. The the unit does exactly what it was designed to do. It is very nice for evaluating the NanoVNA and making sure your setup is working. Just be sure to calibrate on the unit with those cables.

Be aware the connectors on the test cables that connect to the PCB are only good for a hand-full of connection/disconnection cycles before they break

Purchased on a whim mostly for quick sanity checks of various VNA tools and experiments. I have owned various VNAs for many years. This was just a splurge purchase to check it out.Overall the board is well built so can't really fault anything about it except the connectors.UFL connectors are fragile and not intended for more than a few cycles, so this may not last very long is used frequently. As a result, I rarely use it, but it is handy for checking fixtures and measuring techniques.Will be good for students or demonstrations to those new to VNAs if care is taken with the fragile connectors.A breadboard and a handful of components may be more instructional but would likely cost more.

Excellent quality and detail. 5 Star Rating!

I should have looked at the picture more carefully. This test board has IPEX cable connectors. Besides being very small and somewhat tricky to use, these connectors are rated for only a small number of matings (about 30). Disconnection should also be done with a removal tool. This is not really usable.

This one works fine!

Perfect for demoing the NanoVNA to my Ham Radio club.Be careful with the connectors. Install the open end, then snap down the wire end. These conenctors are NOT designed for a LOT of cycles.
