512
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz.
The measurement range defined by means of the center frequency and the current span
([SENSe<Ch>:]FREQuency:SPAN) must not exceed the allowed frequency range of the analyzer.
If necessary, the span is reduced to min (Center – f
MIN
, f
MAX
– Center).
[SENSe<Ch>:]FREQuency:MODE SWEep | SEGMent
Selects the sweep type and defines which set of commands controls the stimulus frequency.
The command [SENSe<Ch>:]SWEep:TYPE provides a complete list of sweep types.
<Ch>
Channel number.
SWEep
Linear or logarithmic frequency sweep, depending on the selected spacing
([SENSe<Ch>:]SWEep:SPACing LINear | LOGarithmic). The frequency
range is set via [SENSe<Ch>:]FREQuency:STARt etc.
SEGMent
Segmented frequency sweep. The sweep range is composed of several continuous
frequency ranges or single frequency points defined by means of the commands in
the [SENSe<Ch>:]SEGMent<Seg>... subsystem.
SCPI,
Command
Types
Confirmed (with device-specific *RST value and parameters), command or query.
Example:
FREQ:MODE SWE
Activate a frequency sweep.
SWE:TYPE LOG
Set the sweep type Log Frequency.
[SENSe<Ch>:]FREQuency:SPAN <span>
Defines the width of the measurement and display range for a frequency sweep.
<Ch>
Channel number.
<span>
Frequency span of the sweep.
Range [def. unit] Depending on the instrument model [Hz]. The increment (parameters UP or
DOWN) is 0.1 kHz.
*RST value Default stop value (depending on the analyzer model) minus default start value
(9 kHz); f
start
– f
stop
