291Operating Manual 1411.4060.32 ─ 09
Example:
FM:SOUR INT
selects the internal modulation source.
Manual operation: See "FM Source" on page 173
[:SOURce<hw>]:FM:STATe <State>
Activates frequency modulation.
Note: Activation of FM deactivates phase modulation (PM).
Parameters:
<State> 0 | 1 | OFF | ON
*RST: 0
Example:
FM:STAT ON
Activates FM modulation.
Manual operation: See "State" on page 173
7.13.4 SOURce:FREQuency Subsystem
This subsystem contains the commands used to define the frequency settings for the
RF sources and sweeps.

[:SOURce<hw>]:FREQuency:CENTer <Center>
Sets the center frequency of the RF sweep range.
The range is defined by this center frequency and the specified [:SOURce<hw>]:
FREQuency:SPAN, according to the formula:
f
CENTer
- (f
SPAN
/2) ... f
CENTer
+ (f
SPAN
/2)
with:
f
SPAN
= f
STOP
- f
STARt
The center frequency directly relates to the span, and the start and stop frequencies. If
you change one of these parameters, the center frequency changes accordingly.
