Attenuation Distortion
The attenuation of the signal in either path is nominally independent of the frequency. The deviations
from nominal attenuation will stay within the limits shown in Figure 6. The reference frequency is
1014 Hz and the signal level is
–
10 dBm0.
Figure 6. Transmit and Receive Path Attenuation vs. Frequency
Minimum transmit attenuation at 60 Hz is 24 dB
Group Delay Distortion
For either transmission path, the group delay distortion is within the limits shown in
Figure 7. The minimum value of the group delay is taken as the reference. The signal level should
be
–
10 dBm0.
