Single Frequency Distortion
Intermodulation 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.
Two sine wave signals of different frequencies, f
to 3400 Hz and of equal levels in the range –4 to –21 dBm0, do not produce 2 • f
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.
