Chapter 2 Command System
[:SOURce[<n>]]:MOD:AM[:DEPTh]
Syntax
[:SOURce[<n>]]:MOD:AM[:DEPTh] <depth>
[:SOURce[<n>]]:MOD:AM[:DEPTh]?
Description
Set or query the AM modulation depth (indicates the amplitude variation degree and is
expressed as a percentage) of the specified source channel. The default unit is %.
Parameter
Name
[<n>]
<depth>
Explanation
In 0% modulation, the output amplitude is half of the carrier waveform amplitude.
In 100% modulation, the output amplitude is equal to the carrier waveform amplitude.
In >100% modulation, envelop distortion which should be avoided in the real circuit will
occur and the output amplitude of the instrument would not exceed 5Vpp (50Ω load).
Return The query returns an integer.

[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency <frequency>
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency?
Description Set or query the modulating waveform frequency of AM or FM of the specified source
channel. The default unit is Hz.
Parameter

amplitude of the modulating waveform.
FM: frequency modulation. The frequency of the carrier waveform varies with the
amplitude of the modulating waveform.

