Description of Arguments
Command or Query.
Sets or returns Rx Sub-Mux Ratio (IP/Synchronous Interface) in the form xx, where:
00=1/9
09=3/7
01=1/8
10=1/2
02=1/7
11=3/5
03=1/6
12=2/3
04=1/5
13=3/4
05=1/4
14=4/5
06=2/7
15=1/1
07=1/3
16=5/4
08=2/5
17=4/3
EXAMPLE: <0/RMR=01 (Selects ratio 1/8)
Command or Query.
Sets or returns Rx Spectrum Invert in the form x, where:
0=Normal
1=Rx Spectrum Invert
EXAMPLE: <0/RSI=0 (selects Normal)
Command or Query.
Sets or returns Rx Descrambler state in the form x, where:
0=Off
1=Normal
2=IESS-315
EXAMPLE: <0/RDS=1 (Scrambler On)
Command or Query.
Sets or returns Rx ± Acquisition Sweep Range of demodulator, in kHz.
Available range depends on the symbol rate:
18ksps to 64ksps:
±1 to the symbol rate (ksps)/2
64ksps to 389ksps:
±1 to the symbol rate (ksps)/2
389ksps to 3000ksps:
±1 to the symbol rate (ksps)/2
>3000ksps:
±1 to the symbol rate (ksps)/2
EXAMPLE: <0/RSW=009 (selects ± 9 kHz)
Command or Query.
Sets or returns Rx Clock Source in the form x, where:
0=Rx Satellite
1=Tx-Terrestrial
2=Internal(SCT)
3=INSERT (command valid only when Rx framing is Insert or D&I++ and interface is G.703 or set for
D&I loop)
EXAMPLE: <0/RCK=1 (selects Tx-Terrestrial)
Command or Query.
Sets or returns Invert Receive Clock, in the form x, where:
0=Normal
1=Inverted
18=3/2
27=6/1
19=5/3
28=7/1
20=2/1
