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 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: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]:FREQuency:CENTer
<f_center> [HZ
|
KHZ
|
MHZ
|
GHZ]
Sets the center frequency of the ramp sweep mode.
[SOURce]:FREQuency:CENTer?
Queries the ramp center frequency. The return value is in Hertz.
[SOURce]:FREQuency:SPAN <f_center>
[HZ
|
KHZ
|
MHZ
|
GHZ]
Sets the span frequency of the ramp sweep mode
[SOURce]:FREQuency:SPAN?
Queries the ramp span 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
|
dB)
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
|
dB)
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.
