AM Programming
Use the following commands for programming the AM parameters.
AM control is internal. The commands for programming the amplitude
modulation function are described below. Note that the carrier
waveform frequency (CW) setting is common to all modulation
schemes.
AM:FUNCtion:SHAPe(SINusoid|TRIangle|SQUare|RAMP}(?)
HS Syntax: 0057A<1|2|3|4>(?)
Description
This command selects one of the waveform shapes as the active modulating waveform.
Parameters
Name
Type
Default
Description
SINusoid
Discrete
SIN
Selects the sine shape as the modulating waveform
TRIangle
Discrete
Select the triangular shape as the modulating waveform
SQUare
Discrete
Select the square shape as the modulating waveform
RAMP
Discrete
Selects the ramp shape as the modulating waveform
Response
The 3152B returns SIN, TRI, SQU, or RAMP depending on the selected function shape setting.
AM:INTernal:FREQuency<am_freq>(?)
HS Syntax: 0781A<float>(?)
Description
This command sets the modulating wave frequency for the built-in standard modulating waveform library.
Parameters
Name
Range
Type
Default
Description
<am_freq>
10e-3 to
1e6
Numeric
100
Programs the frequency of the modulating waveform in
units of Hz. The frequency of the built-in standard
modulating waveforms only is affected.
Response
The 3152B returns the current modulating waveform frequency value. The returned value will be in scientific
notation (for example: 100mHz would be returned as 100e-3).
AM:DEPth<depth>(?)
HS Syntax: 0780A<float>(?)
Description
This command sets the modulating wave frequency for the built-in standard modulating waveform library.
Parameters
Name
Range
Type
Default
Description
<depth>
0 to 100
Numeric
50
Programs the depth of the modulating waveform in units
of percent.
