Use SYSTem:FREQuency? MINimum | MAXimum. to query the frequency range of your analyzer.
Note: For a frequency sweep the range can be defined alternatively by a combination of Start/Stop
frequencies or a Center frequency and Span. In fixed frequency mode (power sweep or Time/CW Mode;
see [SENSe<Chn>:]FUNCtion[:ON]) the measurement frequency is set by means of
[SENSe<Ch>:]FREQuency:CW|FIXed.
[SENSe<Ch>:]FREQuency:CENTer <center_frequency>
Defines the center of the measurement and display range for a frequency sweep.
<Ch>
Channel number. If unspecified the numeric suffix is set to 1.
<center_frequency>
Center frequency of the sweep.
Range [def. unit]
Depending on the instrument model [Hz]. The increment (parameters UP or
DOWN) is 0.1 kHz.
*RST value
Center of the analyzer's maximum frequency range: (f

SCPI, Command
Types
Confirmed, command or query.
Example:
*RST; :SYST:FREQ? MIN; :SYST:FREQ? MAX
Activate a frequency sweep and query the frequency
range of the analyzer.
FREQ:CENT 100MHz
Set the center frequency to 100 MHz.
FREQ:SPAN 50000
Set the frequency span to 50 kHz.
The measurement range defined by means of the center frequency and the current span
([SENSe<Ch>:]FREQuency:SPAN) must not exceed the allowed frequency range of the analyzer. If
necessary, the span is reduced to min (Center – f
MIN
, f
MAX
– Center).
[SENSe<Ch>:]FREQuency:CONVersion FUNDamental | HARMonic | SHARmonic |
THARmonic | MIXer | VMIXer
Enables/disables a frequency converting measurement for channel <Ch>.
