The Sinadder is used for measuring the SINAD of a receiver.
Now sold by Zetron.

SINAD = 20log ((Signal + Noise + Distortion) / (Noise + Distortion))
assuming voltages in each case.
Used as a reference audio output (usually 12dB SINAD) in receiver
sensitivity tests.
Availability: Loads of SINAD meters secondhand. Also included in most
combination test sets.
