
For Example
:CHANnel1:MODulate:SOURce INTernal
Set the modulation source of CH1 to INTernal.
:CHANnel1:MODulate:SOURce?
The query returns INTernal.
:CHANnel<n>:MODulate:FREQuency

Syntax
:CHANnel<n>:MODulate:FREQuency {<freq>}
:CHANnel<n>:MODulate:FREQuency?

Description
Set the modulation frequency for the specified channel’s signal.
<freq> represents frequency, the unit is Hz.
<n>
：
Channel number, n takes value 1, 2.

Return Format
The query returns the modulation frequency of the specified channel’s signal in scientific notation.

For Example
:CHANnel1:MODulate:FREQuency 2000
Set the modulation frequency of CH1 to 2kHz.
:CHANnel1:MODulate:FREQuency? The query returns 2e+3.
:CHANnel<n>:MODulate:ARB

Syntax
:CHANnel<n>:MODulate:ARB <source>,<filename>
:CHANnel<n>:MODulate:ARB?

Description
Set the specified channel to load modulation arbitrary waveform data of a file under arbitrary wave source.
<n>
：
Channel number, n takes value 1, 2.
<source>
：
{INTernal|EXTernal }
，
which is internal and external.
<filename>
：
The filename of arbitrary waveform.

For Example
:CHANnel1:MODulate:ARB INTernal,"AbsSine.bsv"
:CHANnel<n>:MODulate:DEPTh

Syntax
:CHANnel<n>:MODulate:DEPTh { <depth>}
:CHANnel<n>:MODulate:DEPTh?

Description
Set the modulation depth for the specified channel.
<depth> represents the modulation, the unit is %. The rang is 0% ~ 100%, the modulation depth of AM is 0%
