Syntax

[:SOURce[<n>]][:MOD]:AM[:DEPTh] {<depth>|MINimum|MAXimum}

[:SOURce[<n>]][:MOD]:AM[:DEPTh]? [MINimum|MAXimum]

Description

Sets the AM modulation depth of the specified channel.

Queries the AM modulation depth of the specified channel.

Remarks



When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.



Modulation depth indicates the amplitude variation. It is expressed in percentage. When the

modulation depth is 0%, the output amplitude is half of the amplitude of the carrier signal. At 100%

depth, the output amplitude is equal to carrier waveform amplitude. When the modulation depth is

greater than 100%, the output amplitude of the instrument will not exceed 10 Vpp (when the load is

50 Ω).



When the external modulation source (

[:SOURce[<n>]][:MOD]:AM:SOURce

) is selected, the output

amplitude of the instrument is controlled by the ±5 V signal level on the rear-panel [Sync/Ext

Mod/Trig/FSK] connector. For example, if the modulation depth is set to 100%, the output

amplitude will be the maximum when the modulating signal is +5 V and the minimum when the

modulating signal is -5 V.

Return Format

The query returns the AM modulation depth in scientific notation, with 7 effective digits. For example,

5.01 (the AM modulation depth is 50°).

Example

:SOUR1:AM 50 /*Sets the AM modulation depth of CH1 to 50%.*/

:SOUR1:AM? /*Queries the AM modulation depth of CH1 and the query returns 5.01.*/

Remarks



DG900 supports two types of amplitude modulation: normal amplitude modulation and double

sideband suppressed carrier (DSB-SC) amplitude modulation. In the normal amplitude modulation, the

modulated waveform contains carrier waveform components. Because carrier waveform components

carry no information, the modulation is less efficient. In order to improve the modulation efficiency,
