:ERANge ON | OFF
[:SOURce]:FREQuency:CENTer 9 kHz to F
max
(F
max
depending on the model)
The command sets the sweep range by means of the center frequency. This command is
coupled to the commands
[:SOUR]:FREQ:STAR
and
[:SOUR]:FREQ:STOP
.
Here the Offset-value is taken into account.
Example:
:SOUR:FREQ:CENT 300MHz
*RST value is (STARt +STOP)/2
[:SOURce]:FREQuency[:CW | :FIXed] 9 kHz to F
max
(F
max
depending on the model)
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
[:SOUR]:FREQ:STEP
(as to specify range, see
FREQ:CENT
).
Example:
:SOUR:FREQ 500MHz
*RST value is 100 MHz
[:SOURce]:FREQuency: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 [RCL]
key or with a memory sequence.
EXCLude The RF frequency is not loaded when instrument settings are loaded, the current
settings are maintained.
Example:
:SOUR:FREQ:RCL INCL
[:SOURce]:FREQuency:MANual 9 kHz to F
max
(F
max
depending on the model)
The command sets the frequency if
SWE:MODE MAN
and
:FREQ:MODE SWE
are set. Only
frequency values between the settings with
[:SOUR]:FREQ:STAR
and
...:STOP
are permitted.
(As to the permitted range, cf.
FREQ:CENT
).
Example:
:SOUR:FREQ:MAN 500MHz
*RST value is 100 MHz
