Analog Modulation Commands
Amplitude Modulation Subsystem–Option UNT ([:SOURce])
:AM[1]|2[:DEPTh][:LINear]:TRACk
Supported All models with Option UNT
[:SOURce]:AM[1]|2[:DEPTh][:LINear]:TRACk ON|OFF|1|0
[:SOURce]:AM[1]|2[:DEPTh][:LINear]:TRACk?
This command enables or disables AM depth value coupling between AM paths 1 and 2. When the
depth values are coupled, a change made to one path is applied to both. LINear must be the AM type
for this command to have any affect. To set the AM measurement type, use the :AM[1]|2:TYPE
command.
ON (1) This choice will link the depth value of AM[1] with AM2; AM2 will assume the
AM[1] depth value. For example, if AM[1] depth is set to 15% and AM2 is set to
11%, enabling the depth tracking will cause the AM2 depth value to change to
15%. This applies regardless of the path (AM[1] or AM2) selected in this command
OFF (0) This choice disables coupling and both paths will have independent depth values.
Example
:AM1:TRAC ON
The preceding example enables AM depth coupling between AM path 1 and AM path 2.
*RST 0
Key Entry AM Depth Couple Off On
:AM[:DEPTh]:STEP[:INCRement]
Supported All Models with Option UNT
[:SOURce]:AM[:DEPTh]:STEP[:INCRement] <value><unit>
[:SOURce]:AM[:DEPTh]:STEP[:INCRement]?
This command sets the AM depth step increment.
Range 0.1–100%
Key Entry Incr Set
Remarks The value set by this command is used with the UP and DOWN choices for the
AM depth setting. Refer to :AM[1]|2[:DEPTh][:LINear] command for more
information.
The setting enabled by this command is not affected by signal generator power- on,
preset, or *RST.
:AM[1]|2:EXTernal[1]|2:COUPling
Supported All Models with Option UNT
[:SOURce]:AM[1]|2:EXTernal[1]|2:COUPling AC|DC
[:SOURce]:AM[1]|2:EXTernal[1]|2:COUPling?
This command sets the coupling for the amplitude modulation source through the selected external
input connector.
