[:SOURce<n>]:MOD:TYPe
Syntax
[:SOURce<n>]:MOD:TYPe <type>
[:SOURce<n>]:MOD:TYPe?
Description
Set or query the modulation type.
Parameter
Name Type Range Default
<type> Discrete {AM|FM} AM
<n> Discrete {1|2} 1
Explanation
AM: amplitude modulation. The amplitude of the carrier varies with the amplitude of the modulating
waveform.
FM: frequency modulation . The frequency of the carrier varies with the amplitude of the modulating
waveform.
Sine, square, ramp, built-in waveform and arbitrary waveform (except DC) can be used as carrier
waveform.
Sine, square, triangle waveform or noise can be used as modulating waveform. You can use the
[:SOURce<n>]:MOD:AM:INTernal:FUNCtion or [:SOURce<n>]:MOD:FM:INTernal:FUNCtion
command to select the modulating waveform.
Return Format
The query returns AM or FM.
[:SOURce<n>]:MOD:AM[:DEPTh]
Syntax
[:SOURce<n>]:MOD:AM[:DEPTh] {<depth>|MINimum|MAXimum}
[:SOURce<n>]:MOD:AM[:DEPTh]? [MINimum|MAXimum]
Description
Set or query the modulation depth of AM.
Parameter
Name Type Range Default
<depth> Integer 0% to 120% 100%
<n> Discrete {1|2} 1
Return Format
The query returns the current modulation depth in scientific notation.
