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 414
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:CONVersion <ConversionMode>
Enables a frequency conversion measurement mode for channel <Ch>.
Suffix:
<Ch>
.
Channel number
Parameters:
<ConversionMode> FUNDamental | ARBitrary | MIXer | IMODulation
FUNDamental
Measurement of the fundamental signal (non frequency-convert-
ing mode). This selection cancels all port-specific frequency and
power settings (see example).
ARBitrary
Frequency conversion mode (arbitrary port frequencies). This
mode is automatically activated when a port-specific frequency
is defined.
MIXer
Mixer mode, configured using
[SENSe<Ch>:]FREQuency:CONVersion:MIXer... com-
mands.
IMODulation
Intermodulation measurement mode, configured using the
[SENSe<Ch>:]FREQuency:IMODulation... commands.
*RST:
FUNDamental
