[:SOURce[<n>]]:MOD:AM:INTernal:FUNCtion
[:SOURce[<n>]]:MOD:FM:INTernal:FUNCtion
Syntax [:SOURce[<n>]]:MOD:AM:INTernal:FUNCtion <wave>
[:SOURce[<n>]]:MOD:AM:INTernal:FUNCtion?
[:SOURce[<n>]]:MOD:FM:INTernal:FUNCtion <wave>
[:SOURce[<n>]]:MOD:FM:INTernal:FUNCtion?
Description
Set or query the modulating waveform of AM or FM of the specified source channel.
Parameter
Name Type Range Default
[<n>] Discrete {1|2}
If omitted, operating on
source 1 by default
<wave> Discrete {SINusoid|SQUare|RAMP|NOISe} SINusoid
Explanation Sine (SINusoid), Square (SQUare), Ramp (RAMP) or Noise (NOISe) can be selected
as modulating waveform which frequency can be set by sending
[:SOURce[<n>]]:MOD:AM:INTernal:FREQuency or
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency.
Sending the
[:SOURce[<n>]]:MOD:TYPe command can set the modulation type.
AM: amplitude modulation. The amplitude of the carrier waveform varies with the
instantaneous voltage of the modulating waveform.
FM: frequency modulation. The frequency of the carrier waveform varies with the
instantaneous voltage of the modulating waveform.
Return
Format
The query returns SIN, SQU, RAMP or NOIS.
Example
:MOD:AM:INTernal:FUNCtion SQUare
[:SOURce[<n>]]:MOD:FM[:DEVIation]
Syntax [:SOURce[<n>]]:MOD:FM[:DEVIation] <dev>
[:SOURce[<n>]]:MOD:FM[:DEVIation]?
Description Set or query the FM frequency deviation of the specified source channel. The default unit
is Hz.
Parameter
Name
Type
Range
Default
[<n>] Discrete {1|2}
If omitted, operating on
source 1 by default
<dev> Real
0Hz to the carrier waveform
frequency
10kHz
Explanation Sending [:SOURce[<n>]]:FREQuency[:FIXed] can set the carrier waveform
frequency and sending
[:SOURce[<n>]]:MOD:FM:INTernal:FREQuency can set the
FM modulation frequency.
When the modulating waveform amplitude reached to its maximum, the carrier
waveform frequency increases frequency deviation. When the modulating
waveform amplitude reached to its minimum, the carrier waveform frequency
decreases frequency deviation.
Return
Format
The query returns an integer.
Example
:MOD:FM 100
