Source Specific
Command
Description
Sets the frequency of the internal modulating
waveform only. The default frequency is 10Hz.
Syntax
SOURce[1|2|3|3RF]:FM:INTernal:FREQuency
{<frequency>|MINimum|MAXimum}
Parameter
<frequency>
2 mHz~ 20 kHz
Example
SOUR1:FM:INT:FREQ 100
Sets the modulating frequency to 100Hz.
Query Syntax
SOURce[1|2|3|3RF]:FM:INTernal:FREQuency?
[MINimum|MAXimum]
Return Parameter
<NR3>
Returns the frequency in
Hz.
Example
SOUR1:FM:INT:FREQ?
+1.0000E+02
Returns the frequency to 100Hz.
SOURce[1|2|3|3RF]:FM:DEViation
Source Specific
Command
Description
Sets or queries the peak frequency deviation of the
modulating waveform from the carrier waveform.
The default peak deviation is 100Hz.
The frequency deviation of external sources is
controlled using the ±5V MOD INPUT terminal on
the rear panel. A positive signal (>0~+5V) will
increase the deviation (up to the set frequency
deviation), whilst a negative voltage will reduce
the deviation.
Note
The relationship of peak deviation to modulating
frequency and carrier frequency is shown below.
Peak deviation = modulating frequency – carrier
frequency.
