[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 analyzer:
f
MAX
–
f
MIN
. The range is listed in table
.
Suffix:
<Ch>
.
Channel number
Parameters:
<Span>
Frequency span of the sweep
Increment: 0.1 kHz
Default unit: Hz
Example:
See
Manual operation:
See
"Start / Stop / Center / Span Frequency (Power / Time)"
Note:
The measurement range defined by means of the span and the current 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 values
also define display range in a Cartesian diagram. The default start and stop frequencies
equal to the minimum and maximum frequency of the analyzer.
The ranges are listed in table
.
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 / Stop / Center / Span Frequency (Power / Time)"
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 (
).
