P300H P300 Series Modem Installation and Operating Handbook
Better than - 55dBc/4 kHz
55dB minimum
By external contact closure or by TTL signal applied to rear panel
connector. Hardware function overrides processor control
P300: -45dBm nominal, ±15dB (desired carrier)
P310: -20 to -70dBm (desired carrier)
P300: 30dB above level of desired input up to a maximum of 0dBm
P310: 35dB above level of desired input up to a maximum of -10dBm
Selectable from ± 1 kHz to ± 32 kHz
< 5dB Eb/No
@ 9.6 kbps < 3 seconds at 6dB Eb/No
@ 64 kbps < 2 seconds at 6dB Eb/No
@ 2048 kbps < 500 ms at 6dB Eb/No
± 100 ppm min
6th order Butterworth, group delay equalised (INTELSAT IESS compliant)
In all cases met in the presence of two adjacent carriers each 10dB
higher than the desired carrier, with V.35 scrambling
These figures meet or exceed the relevant IESS performance
specifications.
