4.2.4.12 AM (FM, PM) Source
Functional Description:
This command selects AM (FM, PM) Source, including: INT and EXT, you need to connect the
external AM (FM, PM) signal to the AM (FM, PM) input ports on the front panel of the signal generator
in EXT mode.
Parameter specification:
<Mode>
Discrete data.
AM (FM, PM) Source is as follows:
EXTernal
EXT AM (FM, PM),
INTernal
INT AM (FM, PM).
Programmable command:
[:SOURce]:AM(FM
、
PM):SOURce EXTernal|INTernal
[:SOURce]:AM(FM
、

Example:
:AM(FM
、
PM):SOURce INT
AM (FM, PM) Source is in INT mode.
4.2.4.13 AM Depth [ON/OFF]
Functional Description:
This command sets AM mode. In DEEP mode, AM Depth of the signal generator is dynamically
greater than that when ALC Loop is turned off, and AM index is superior to the index in data manual;
in NORMal mode, AM index is the same as that in data manual. Please refer to data index of S1465
series signal generator.
Parameter specification:
<Mode>
Discrete data. AM Mode is as follows:
DEEP
AM Depth is turned on,
NORMal
AM Depth in turned off.
Programmable command:
[:SOURce]:AM:MODE DEEP|NORMal
[:SOURce]:AM:MODE
？
Example:
:AM:MODE NORM
AM Depth is turned off.
4.2.4.14 AM (FM,PM) Rate
Functional Description:
This command sets the internal AM (FM,PM) rate of the signal generator. It can also set the first
tone when AM (FM, PM) Waveform is DualSinc, and Freq Start when AM (FM, PM) Waveform is
SweepSinc.
