The level of an unwanted signal above the level of a wanted signal
that will reduce the SINAD of the wanted signal from 20dB SINAD to
14dB
SINAD
Blocking (MUS)
-20 kHz and +20 kHz
better than 71dB
The level of an unwanted signal above the level of a wanted signal
that will reduce the SINAD of the wanted signal from by 6dB or cause
and output level change of 3dB.
Blocking (+60dbuV)
-20 kHz and +20 kHz better than 60dB (+110dBuV)
The level of an unwanted signal above the level of a wanted signal
that will reduce the SINAD of the wanted signal from by 6dB or cause
and output level change of 3dB.
Intermodulation
better than 89dbµV
The level of two unwanted signals, that are within 30kHz of the
wanted signal, above the level of a wanted signal that reduces the
SINAD of the wanted signal to 20dB.
Spurious response ratio
Better than 70dB
Reciprocal mixing
Better than 105 dBµV
In-band IMD
