[:SOURce<hw>]:FM:MODE <Mode>
Selects the mode for the frequency modulation.
Parameters:
<Mode> NORMal | LNOise
NORMal
The maximum range for modulation bandwidth and FM deviation
is available.
LNOise
Frequency modulation with phase noise and spurious character-
istics close to CW mode. The range for modulation bandwidth
and FM deviation is reduced (see data sheet).
*RST: NORMal
Example: See Example "Creating a frequency modulated RF signal"
on page 969.
Manual operation: See "Mode" on page 544
[:SOURce<hw>]:FM:SENSitivity?
Queries the sensitivity of the externally supplied signal for frequency modulation. The
sensitivity depends on the set modulation deviation.
Return values:
<Sensitivity> float
Sensitivity in Hz/V.
It is assigned to the voltage value for full modulation of the input.
Range: 0 to max
Increment: 0.01
Example: See Example "Using an external signal source" on page 971.
Usage: Query only
14.19.3.4 SOURce:PM Subsystem
Option: R&S SMW-K720
The PM subsystem contains the commands for setting the phase modulation. You can
configure the internal modulation source (LF generator) with the commands listed in
Chapter 14.19.11, "SOURce:LFOutput Subsystem", on page 1152 .
For information about the required options, see Chapter 8.8.1, "Required Options",
on page 531.
Example: Performing phase modulation
The following example shows a command sequence to perform phase modulation.
