15.4Automatic Uplink Power Control

Operating Mode

Target Eb/No range

Max AUPC range

Monitor functions

Requires Closed Network Framed mode (EDMAC, D&I++, or ESC++) for transport of Eb/No information from remote modem (EDMAC can be enabled or disabled)

0 to 9.9 dB at remote demod (default is 4.0 dB)

0 to 9 dB (default is 3 dB)

Remote demod Eb/No Tx power level increase

(front panel or via remote control interface)
