SDM-650B Satellite Modem Trojan Interface
Rev. 5 G–27
G.6.4.2.9 Sweep Width Range
This command sets the overall travel of the sweep during acquisition. The sweep width may
be set in the range of 0 to 50000 Hz.
Command: <add/SWR_nnnnn”cr”
Response: >add/SWR_nnnnn”cr””lf”]
Status Only: <add/SWR_”cr”
Response: >add/SWR_nnnnn”cr””lf”]
Where: nnnnn = 0 to 50000.
Note: This command is only valid when Fast Acquisition is enabled. See the “FAM_”
command definition.
G.6.4.2.10 Sweep Direction
This command sets the direction of the sweep travel. “+” sets incremental sweep, while “-”
sets decremental sweep.
Command: <add/SD_s”cr”
Response: >add/SD_s”cr””lf”]
Status Only: <add/SD_”cr”
Response: >add/SD_s”cr””lf”]
Where: s = + or - (direction of sweep travel during acquisition).
Note: This command is only valid when Fast Acquisition is enabled. See the “FAM_”
command definition.
G.6.4.2.11 Bit Error Rate Threshold
Command: <add/BERT_xxxx”cr”
Response: >add/BERT_xxxx”cr””lf”]
Status Only: <add/BERT_”cr”
Response: >add/BERT_xxxx”cr””lf”]
Where: xxxx = NONE or 1E-n (n = 3, 4, 5, 6, 7, or 8 [exponent of threshold]).
