[:SOURce<n>]:MOD:FM[:DEVIation]
Syntax
[:SOURce<n>]:MOD:FM[:DEVIation] {<dev>|MINimum|MAXimum}
[:SOURce<n>]:MOD:FM[:DEVIation]? [MINimum|MAXimum]
Description
Set or query the frequency deviation of FM of the specified signal source channel. The default unit is Hz.
Parameter
Name Type Range Default
<dev> Real
0Hz to the current frequency of the carrier waveform. The
sum of the frequency deviation and carrier frequency cannot
be greater than the sum of the upper limit of the carrier
frequency and 1kHz.
1kHz
<n> Discrete {1|2} 1
Return Format
The query returns the current frequency deviation in scientific notation.
[:SOURce<n>]:MOD:FM:INTernal:FREQuency
Syntax
[:SOURce<n>]:MOD:FM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce<n>]:MOD:FM:INTernal:FREQuency? [MINimum|MAXimum]
Description
Set or query the modulating waveform frequency of FM of the specified signal source channel. The default
unit is Hz.
Parameter
Name Type Range Default
<frequency> Real 1Hz to 50kHz 1kHz
<n> Discrete {1|2} 1
Return Format
The query returns the current modulating waveform frequency in scientific notation.
