3.3.28 Start/Stop Swept Frequency Source Mode Def. Cmd.
Structure
SWPF
Syntax: SWPF us [us modifier]..[us modifier]
Modifiers: This modifier defines a start frequency for the start/stop swept frequency mode of signal
source. The query flag (‘?’) affixed to the start frequency modifier queries the value of the
start frequency. If set, the next time the 8003 is talk-addressed it will output the value of
the start frequency in MHZ. The format of the returned data is D.dddddd, where D is zero
to 6 digits and the assumed units are MHZ
Modifier name: START, START?, FA, FA?
Modifier Syntax: FA[?] [ds numerical value]
numerical value range: Dependent upon the signal source if the source is
supported on the 8003’s private bus. If not supported
then the range is 1 MHZ to 99 GHZ
Modifier Description: This modifier defines a stop frequency for the start/stop
swept frequency mode of signal source. The query flag
(‘?’) affixed to the stop frequency modifier queries the
value of the stop frequency. If set, the next time the 8003
is talk-addressed it will output the value of the stop
frequency in MHz. The format of the returned data is
D.dddddd, where D is zero to 6 digits and the assumed
units are MHZ
Modifier name: STOP, STOP?, FB, FB?
Modifier Syntax: FB[?] [hs numerical value]
numerical value range: Dependent upon the signal source if the source is
supported upon the 8003 private bus. If not supported
then the range is 1 MHZ to 99 GHZ
Description: This modifier defines a POWER LEVEL for the start/stop
swept frequency mode of signal source. The query flag
(‘?’) affixed to the power level modifier queries the value
of the power level. If set, the next time the 8003 is talk-
addressed it will output the value of the power level in
dBm. The resolution is 0.01 dBm. The format of the
returned data is
±
D.dd, where D is zero to three digits
and the assumed units are dBm
Modifier name: LEVEL, LEVEL?, PL, PL?
Modifier Syntax 1: PL[?] [hs numerical value]
numerical value range: Dependent upon the signal source if the source is
supported on the 8003’s private bus. If not supported
then the range is -99 to +99 dBm.
Modifier Syntax 2: PL hs on
State definition: OFF, ON
