Re: What accessories do I need for a TinySA Ultra?

 

Some people like to have a spare or backup set of calibration kits in case one gets lost or misplaced.
Myself, I have a set for my NanoVNA H and a set for my H4.
Both NanoVNAs are in separate cases with all adapters for each.
Some use only one set for multiple VNAs.
It is a individual choise.
You will find the less expensive ones vary in resistor value.
As an experiment I purchased 4 of the load parts of the cal. kits from different vendors and checked each load for actual value. Each was different. I then chose which ones was closest to 50 ohms and use those. I put the others in a spare parts or junk bin.
Unless you buy the very expensive certified cal. kits, you will find most load parts in the inexpensive kits will run around 49.** ohms and 51.** ohms.

What is the second calibration kit for the NanoVNA for? Or what kit should I buy off of amazon to do it? I have the calibration kit that came with the NanoVNA, can you post a link to the one I should get?

And maybe some links to attenuators that are worth buying?
