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, f1 and f2 (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 • f1 – f2 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.
