[SENSe<Ch>:]FREQuency:SPAN <Span>
Defines the width (span) of the measurement and display range for a frequency sweep
(sweep range). The default span equals to the maximum frequency range of the ana-
lyzer: f
MAX
–
f
MIN
. The range depends on the instrument model; see Table 7-13
Suffix:
<Ch>
.
Channel number
Parameters:
<Span> Frequency span of the sweep
Increment: 0.1 kHz
Default unit: Hz
Example: See
[SENSe<Ch>:]FREQuency:CENTer
Manual operation: See "Start Frequency / Stop Frequency / Center Frequency /
Span Frequency" on page 430
Note: The measurement range defined by means of the span and the current center
frequency (
[SENSe<Ch>:]FREQuency:CENTer
), must not exceed the allowed fre-
quency 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 <StartFreq>
[SENSe<Ch>:]FREQuency:STOP <StopFreq>
These commands defines the start and stop frequency for a frequency sweep. The val-
ues also define display range in a Cartesian diagram. The default start and stop fre-
quencies equal to the minimum and maximum frequency of the analyzer.
The ranges depend on the instrument model; see table Table 7-13 .
Suffix:
<Ch>
.
Channel number
Parameters:
<StopFreq> Start and stop frequency of the sweep
Increment: 0.1 kHz
Default unit: Hz
Example: *RST; FREQ:STAR 100000
Activate a frequency sweep and set the start frequency to 100
kHz.
FREQ:STOP 10MHz
Set the stop frequency to 10 MHz.
Manual operation: See "Start Frequency / Stop Frequency / Power CW Frequency"
on page 386
Note: If the start frequency entered is greater than the current stop frequency, the stop
frequency is set to the start frequency plus the minimum frequency span
(
[SENSe<Ch>:]FREQuency:SPAN
).
