This screen allows the target Eb/No to be set. This It is the distant Eb/No when the AUPC mode It is set
to
Ó¿·²¬ù Û¾ñÒ±
, and the local Eb/No when set to
Í»´º Ó±²
. This It is the target Eb/No the AUPC will
adjust the Tx power within the Max, Min, and Slew rate limits (once the Eb/No goes outside the
Tolerance window set below) to try and restore this figure.
6.6.23 Change, Tx, Modulator, AUPC, TOLERANCE Menu
Set Eb/No tolerance before AUPC action:
[ 0.5dB] (0.1-25.0dB) ??.?dB (Yes)
Change, Tx, Modulator, AUPC, Tolerance Menu
This sets a `tolerance window` on the monitored Eb/No. The AUPC will only attempt to restore the
monitored Eb/No to the target Eb/No when the monitored Eb/No moves outside the tolerance window.
This It is to prevent the AUPC continuously adjusting the power to compensate for minor normal Eb/No
variations.
When the monitored Eb/No moves outside the tolerance window the AUPC will attempt to restore it back
to the
target value (ie not just back inside the tolerance window again).
