SOURce:AM R&S®SML / R&S®SMV03
1090.3123.12 E-6 6.14
[:SOURce]:AM:EXTernal
The c
ommands to set the external AM input are under this node.
[:SOURce]:AM:EXTernal:COUPling AC | DC
The command selects the type of coupling for the external AM input.
AC The d.c. voltage content is separated from the modulation signal.
DC The modulation signal is not altered. *RST value is AC
Example: :SOUR:AM:EXT:COUP AC
[:SOURce]:AM:INTernal
The settings for the internal AM input are effected under this node.
Here the same hardware is set for AM, FM/M and SOURce2. This means that, for example, the
following commands are coupled to each other and have the same effect:
SOUR:AM:INT:FREQ
SOUR:FM:INT:FREQ
SOUR:PM:INT:FREQ
SOUR2:FREQ:CW
[:SOURce]:AM:INTernal:FREQuency 0.1Hz to 1 MHz
The command sets the modulation frequency.
Example: :SOUR:AM:INT:FREQ 15kHz *RST value is 1 kHz
[:SOURce]:AM:SOURce EXTernal | INTernal | TTONe
The command selects the modulation source. An external and an internal modulation source can
be specified at the same time.
Example:
:SOUR:AM:SOUR EXT,INT
*RST value is INT *RST value is INT
[:SOURce]:AM:STATe OFF | ON
The command switches amplitude modulation on or off.
Example: :SOUR:AM:STAT ON *RST value is OFF
