SDM-100A Satellite Modem Remote Control Operation
Rev. 0 A–21
Current
Sweep
Value Command:
Response: <add/CSV_'cr'
>add/CSV_snnnnn'cr''lf']
Where:
x = < or > (data modifier to indicate that the sweep offset
value is less than or greater than the returned value).
s = + or - (sweep offset from center).
nnnnn = 0 to 35000.
Notes:
1. This command returns the current sweep offset value.
2. The 'x' (< or >) parameter is only returned if the level
has exceeded the computational resolution of the
system.
3. "No Data" is returned if the level cannot be calculated.
4. "Sampling" is returned if not enough data is currently
available to calculate the level.

Status
Status:
Response: <add/ALBJ_'cr'
>add/ALBJ_xxx'cr''lf']
Where: xxx = ON or OFF.
Note: Only valid when ADPCM board is installed.
Bulk Consol
Analog
Status Command:
Response: <add/BCAS_'cr'
>add/BCAS_p1,p2,p3, . . . pn'cr''lf']
This command is similar to the 'BCS_' command but,
returns modem analog parameters.
Where 'pn' is the last parameter returned.
Parameter 1 (p1): Receive Signal Level (ref. "RSL_"
command).
p1 = xsnn.n, receive signal level in dBm.
Parameter 2 (p2): Raw BER (ref. "RBER_" command).
p2 = xm.m -ee .
Parameter 3 (p3): Corrected BER (ref. "CBER_"
command).
p3 = xm.m -ee .
Parameter 4 (p4): E
b
/N
0
(ref. "EBN0_" command).
p4 = xnn.n, E
b
/N
0
in dB.
Parameter 5 (p5): Current Sweep Value (ref. "CSV_"
command).
p5 = snnnnn, sweep offset value in Hz.
Note: Parameters 2 through 5 are dependent on carrier
acquisition, if the decoder is not locked empty data blocks
are returned (,,,,).
