Instrument-Control Commands
Operating Manual 1303.6580.32-05
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
.
SCPI, Command
Types
Confirmed, command or query.
Example:
FUNC "XFR:POW:RAT B1, A2"
