Easy for you to ask. I doubt any store has the device. And the

There is no such thing as a .00000000001 dB signal


Whats stops a .00000000001 dB signal from existing?


Nothing, it's just indistinguishable from a 0db signal.

In other words it's about half the amplitide of a 3db signal...

It's a logarythmic scale.

No, without a reference, its use is meaningless. He was trying to
use dB for an absolute signal level, not a ratio.
