XT 127 Spectrumanalyzer versus TinySA

I have bought the XT-127 from Bangood for I supposed it must at least perform as well as the 5 times cheaper TinySA...... what a disappointment

it became to me the XT-127 is $339.89 and the TinySA is only a fraction of this sum and performs way better.
I'm really pissed off having bought this ST-127 it is a waste of money though it is well build nicely packed and has some interesting features but all this is in vain when there is no sensitivity and the SA also creates a very good audible noise floor in the adjacent radio like a wobble generator and it seems the SA picks up it's very own noise too.

Arghhh....

I confirm what Erwin wrote because I tested the XT-127 and a TinySA. TinySA behaves well, but unfortunately it can only measure up to 960MHz, which is why I tried XT-127.
