Rev. 6 B–15
B.1.3.22.1 Sweep Center Frequency
This command sets the sweep center frequency. During carrier acquisition, the sweep
starts at an offset, which is one-half the currently programmed sweep range (SWR_) from
the sweep center frequency. The direction of the offset is determined by the currently
programmed sweep direction (SD_).
The sweep center frequency may be set in the range of +25000 to -25000 Hz.
Command:
Response: >add/SCF_xnnnnn”cr””lf”]
Status Only: Response:
>add/SCF_xnnnnn”cr””lf”]
Where:
x = + or - (sweep offset direction).
nnnnn = 0 to 25000.
Note: This command is only valid when fast acquisition is enabled. See the “FAM_”
command definition.
B.1.3.22.2 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 Hz to 50000 Hz.
Command:
Response: >add/SWR_nnnnn”cr””lf”]
Status Only: 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.
