[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 Maximum frequency range of the analyzer: f
MAX
- f
MIN
SCPI, Command
Types Confirmed, command or query.
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as
measured parameter for channel and trace no. 1.
FREQ:CENT 100MHz
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz, leaving the center frequency
unchanged.
Note: The measurement range defined by means of the span and the current center frequency
([SENSe<Ch>:]FREQuency:CENTer), must not exceed the allowed frequency range of the
analyzer. If necessary, the center frequency is adjusted to f
MIN
+ Span/2 or f
MAX
– Span/2.
[SENSe<Ch>:]FREQuency:STARt <start_frequency>
Defines the start frequency for a frequency sweep which is equal to the left edge of a Cartesian
diagram.
<Ch> Channel number.
<start_frequency> Start frequency of the sweep.
Range [def. unit] Depending on the instrument model [Hz]. The increment
(parameters UP or DOWN) is 0.1 kHz.
*RST value Minimum frequency of the analyzer: MIN
SCPI, Command
Types Confirmed, command or query.
Example:
FUNC "XFR:POW:RAT B1, A2"
Activate a frequency sweep and select the ratio B1/A2 as
measured parameter for channel and trace no. 1.
FREQ:STAR 100000
Set start frequency to 100 kHz.
FREQ:STOP 10MHz
Set stop frequency to 10 MHz.
Note: If the start frequency entered is greater than the current stop frequency
([SENSe<Ch>:]FREQuency:STOP), the stop frequency is set to the start frequency plus the
minimum frequency span ([SENSe<Ch>:]FREQuency:SPAN).
