Command Syntax
Description
[SOURce]:FREQuency:STARt <f_start> [HZ | KHZ |
MHZ | GHZ]
Sets the ramp start frequency to the value
specified by <f_start>. Hertz is assumed as the
units if units are not specified.
The start frequency must be set less than the stop
frequency. If this rule is violated, the start and stop
frequencies are set to the same value.
[SOURce]:FREQuency:STARt?
Queries the ramp start frequency. The return value
is in Hertz.
[SOURce]:FREQuency:STOP <f_stop> [HZ | KHZ |
MHZ | GHZ]
Sets the ramp stop frequency to the value
specified by <f_stop>. Hertz is assumed as the
units if no units is specified. The start frequency
must be set less than the stop frequency. If this
rule is violated, the start and stop frequencies are
set to the same value.
[SOURce]:FREQuency:STOP?
Queries the ramp stop frequency. The return value
is in Hertz.
[SOURce]:SWEep: TIME <time>
Sets the sweep time for ramp sweep to the value
specified by <time>. The units are seconds.
[SOURce]:SWEep:TIME?
Queries the sweep time for ramp sweep. The
return value is in seconds.
[SOURce]:POWer:STARt d (DM | DBM | dBV)
Sets the ramp sweep start power level. The
assumed units are defined as DM, DBM, or dBV.
[SOURce]:POWer:STARt?
Queries the ramp start power. The return value is
in dBm.
[SOURce]:POWer:STOP d (DM | DBM | dBV)
Sets the ramp sweep stop power level. The
assumed units are defined as DM, DBM, or dBV.
[SOURce]:POWer:STOP?
Queries the ramp stop power. The return value is
in dBm.
[SOURce]:POWer:SPAN d
Sets the amplitude span
[SOURce]:POWer:SPAN?
Queries the amplitude span
