User Manual 1173.9163.02 ─ 55
Parameters:
<FixedFreq>
Fixed stimulus and analyzer frequency
*RST:
1 GHz
Default unit: Hz
Example:
FUNC "XTIMe:POW:A1"
Activate a time sweep and select the wave quantity a
1
as mea-
sured parameter for channel and trace no. 1.
FREQ:CW 100MHz
Set the CW frequency to 100 MHz.
Manual operation:
See
[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
.
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 /
Note:
The measurement range defined by means of the center frequency and the cur-
rent span (
) must not exceed the allowed frequency
range of the analyzer. If necessary, the span is reduced to min (<CenterFreq>
–

–
<CenterFreq>).
[SENSe<Ch>:]FREQuency:CONVersion
<ConversionMode>
Enables a frequency conversion measurement mode for channel
