Single Frequency Distortion
The output signal level, at any single frequency in the range of 300 to 3400 Hz, other than that due
to an applied 0 dBm0 sine wave signal with frequency f in the same frequency range, is less than
–
46 dBm0. With f swept between 0 to 300 Hz and 3.4 to 12 kHz, any generated output signals other
than f are less than
–
28 dBm0. This specification is valid for either transmission path.
Intermodulation Distortion
Two sine wave signals of different frequencies, f
1
and f
2
(not harmonically related) in the range 300
to 3400 Hz and of equal levels in the range
–
4 to
–
21 dBm0, do not produce 2
f
1
–
f
2
products
having a level greater than
–
42 dB, relative to the level of the two input signals.
A sine wave signal in the frequency band 300 to 3400 Hz with input level
–
9 dBm0 and a 50 Hz
signal with input level
–
23 dBm0 does not produce intermodulation products exceeding a level of
–
56 dBm0. These specifications are valid for either transmission path.
