[SENSe<Ch>:]FREQuency:CENTer <CenterFreq>
Defines the center of the measurement and display range for a frequency sweep
(sweep range). The default center frequency is the center of the analyzer's maximum
frequency range: (f
MIN
+ f
MAX
)/2. The range depends on the instrument model; see
Table 7-17.
Suffix:
<Ch>
.
Channel number
Parameters:
<CenterFreq> Center frequency of the sweep
Increment: 0.1 kHz
Default unit: Hz
Example:
*RST; :SYST:FREQ? MIN; :SYST:FREQ? MAX
Query the frequency range of the analyzer.
FREQ:CENT 100MHz
Set center frequency to 100 MHz.
FREQ:SPAN 50000
Set frequency span to 50 kHz.
Manual operation: See "Start Frequency / Stop Frequency / Center Frequency /
Span Frequency" on page 523
Note: The measurement range defined by means of the center frequency and the cur-
rent span ([SENSe<Ch>:]FREQuency:SPAN) must not exceed the allowed frequency
range of the analyzer. If necessary, the span is reduced to min (<CenterFreq> – f
MIN
,
f
MAX
– <CenterFreq>).
[SENSe<Ch>:]FREQuency:COMPression:POINt <CompVal>
Defines the compression value for a gain compression measurement in channel <Ch>.
The gain compression measurement searches for the <CompVal> dB compression
points.
Suffix:
<Ch>
.
Channel number
Parameters:
<CompVal> Compression value
