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.
