[:SOURce]:FREQuency:CENTer 5 kHz to 1.5 GHz (SME03E/03/06: 5 kHz to 2.2/3/6 GHz)
The command sets the sweep range by means of the center frequency. This command is coupled
to commands :SOURce:FREQuency:STARt and :SOURce:FREQuency:STOP.
In this command, value OFFSet is considered as with input value FREQUENCY in the
FREQUENCY menu. Thus the specified range indicated is only valid for OFFSet = 0. The
specified range with other OFFSet values can be calculated according to the following formula (cf.
Chapter 2, Section "Frequency Offset" as well):
5 kHz + OFFSet to 1.5 GHz +OFFSet *RST value is (STARt +STOP)/2
Example: :SOUR:FREQ:CENT 100kHz
[:SOURce]:FREQuency[:CW|:FIXed] 5 kHz to 1.5 GHz (SME03E/03/06: 5 kHz to 2.2/3/6 GHz)
The command sets the frequency for CW operation. This value is coupled to the current sweep
frequency. In addition to a numeric value, UP and DOWN can be indicated. The frequency is
increased or reduced by the value set under :SOURce:FREQuency:STEP. (As to specified
range, cf. FREQuency:CENTer).
Example: :SOUR:FREQ:CW 100kHz *RST value is 100 MHz
[:SOURce]:FREQuency[:CW|:FIXed]:RCL INCLude | EXCLude
The command determines the effect of the recall function on the frequency. *RST value has no
effect to this setting.
INCLude The saved frequency is loaded when instrument settings are loaded with the
[RECALL] key or with a memory sequence.
EXCLude The RF frequency is not loaded when instrument settings are loaded, the current
settings are maintained.
