Parameters
Serial Remote Control
Description of Arguments
Command or Query.
Sets or returns Tx Carrier State in the form x, where:
0=OFF due to front panel or remote control command
1=ON
2=RTI (receive/transmit inhibit), timeout=10 seconds
3=OFF due to ext H/W Tx Carrier- Off control *
4=OFF due to BUC or High-Stability Ref warm-up *
5=Carrier controlled by STDMA Controller *
6=RTI (receive/transmit inhibit), timeout=1 second
7=RTI (receive/transmit inhibit), timeout=2 seconds
8=RTI (receive/transmit inhibit), timeout=4 seconds
9=RTI (receive/transmit inhibit), timeout=7 seconds
NOTE: Arguments indicated with a * are status-only. They are not valid as a command, and are not
indicated in MGC? response.
EXAMPLE: <0/TXO=1 (Tx Carrier ON)
Command or Query.
Sets or returns Tx Alpha Filter Rolloff Factor in the form x, where:
0=0.35
1=0.25
2=0.20
3=0.15
4=0.10
5=0.05
EXAMPLE: <0/TXA=0 (Tx filter rolloff factor is 0.35)
Command or Query.
Sets or returns Power Level Mode in the form x, where:
0=MANUAL mode (AUPC disabled) – Normal power mode
1=AUPC enabled.
2=MANUAL-LOW – Low power mode (-65 to -20dBm) - external attenuator activated.
3=AUPC-LOW – AUPC enabled and external attenuator activated
EXAMPLE: <0/AUP=1 (AUPC Enabled)
NOTE: EDMAC or D&I++, or E1 D&I w/ccs framing must be selected for the AUPC feature to be
available.
Command or Query.
Sets or returns AUPC operating parameters in the form abc.cd, where:
a=Action on max. power condition: (0=do nothing, 1=generate Tx alarm)
b=Action on remote demod unlock: (0=go to nominal power, 1=go to max power)
c.c=Target Eb/No value, in dB, for remote demod from 0.0 thru 14.9:
Numbers above 9.9 use hex representation for the first character, i.e. 14.9 is coded as E.9.
d =Max increase in Tx Power permitted, in dB, from 0.0 thru 9.0
EXAMPLE: <0/APP=015.67 (Sets no alarm, max power, 5.6 dB Target and 7 dB power increase.)
