Re: [Amateur-repairs] SETTING UP A TEST BENCH

It is the TinySA and TinySA Ultra. Limited places to buy real ones from but their listed in the TinySA Wiki. The dealers not in the list are most likely selling clones that wont update correctly and fail self test.

From China,  order from Aliexpress Zeenko store. They are one of the authorized sellers and probably the cheapest.

I was told that there is a tiny spectrum analyzer that works amazingly well from
China. It sells for under $100.
