Garosa Frequency Test Board Demo Kit VNA Test Module Vector Network Analyzer Breadboard Test Protoboard Board Filter/Attenuator Module

If you are new to VNAs, this is an excellent tool to learn to interpret the results on a Smith chart. If you're looking to buy, or have bought a Nano VNA or similar I highly recommend this. The only downside is that the U.FL connectors used have a very finite lifetime. Too many connection cycles and they will wear out. Still for the cost it's hard to beat! Remember to calibrate your VNA before measuring, using the open, short, and load on the board, and the cables you will be using. If you calibrate at the ports of the VNA the results will be wrong when you measure through cables, because of the phase shift introduced by the cables. It's really inexpensive, you might just buy two!

Worked as in intended. Very Happy to have a good reference. It's a good Hamradio teaching tool.

I used it to calibrate a VNA. It worked just fine.

The test board is a great value, the connectors mounted on the board are difficult to connect, and very fragile. People would have been willing to pay a little more for a test board with better connectors.

Garosa Frequency Test Board Demo Kit VNA Test Module works as advertised and promises to add value to my RF test instrument capability.

Nice!

I thought this was a great device to learn about the VNA especially for the price. To those of your who complained about the micro connectors, just be more careful! --this is a learning device and you won't be using it your whole life! I have big fat hands and I managed ok with a little TLC.

Repeated use of the board will damage the connectors on the board. They are not made for multiple disconnection & reconnects. Although it would raise the price of the device, a higher quality & different style of connector would be better.

I have purchased this demo kit for the demo purposes to the students. These are working good and very useful to demonstrate the use of nano VNA.

Excelente produto.

Un compagnon très utile au VNA

There is NO documentation with this board, no schematic, no circuit descriptions, no support at all.

The board arrived on time and is of good quality. The price was also much lower than similar items sold on eBay. The reason for only 4 stars is the quality of the connectors installed on the board, but that is a design issue. Thank you!
