Spurious in-band signal
When a sine wave signal in the range of 700-1100 Hz, at a level of 0 dBmO
is applied to the input port, the output level (at any frequency other than that
of the applied signal,) is less than -40 dBmO when measured selectively in
the band 300-3400 Hz.
Spurious out-of-band signal
When a sine wave signal in the range of 300-3400 Hz, at a level of 0 dBmO
is applied to the input port, the level of spurious out-of-band image signals
measured selectively at the output port is lower than -25 dBmO.
Discrimination against o ut-of-band signals
With any sine wave signal above 4.6 kHz applied to the input port at -25
dBm0, the level of any image frequency produced at the output is at least 25
dB below the level of the test signal.
Intermodulation
When two sine wave signals, f1 and f2, in the range of 450 to 2050 Hz, not
harmonically related and of equal level in the range -21 to -4 dBmO are
applied to the input, they do not create any 2f2-f1 intermodulation product
greater than 35 dB below the power level of the input signal.
