[:SOURce]:LFOutput:FREQuency:ALTernate:AMPLitude:PERCent <Percent>
Function:
This command is used for setting the percentage of amplitude of second tone to that of
total output signal in dual sine waveform when LF Waveform is set to DualSinc; for
example, if the second tone accounts for 20% of the total waveform power, the first
tone will account for 80% of the total power output.
Setting format:
[:SOURce]:LFOutput:FREQuency:ALTernate:AMPLitude:PRECent <val>
Query format:
[:SOURce]:LFOutput:FREQuency:ALTernate:AMPLitude:PRECent
？
Parameter:
<Percent> Amplitude percentage of frequency 2 of dual sine.
Range: 50 [0
，
100].
Example:
:LFOutput:FREQuency:ALTernate:AMPLitude:PRECent 20
Set the percentage of second waveform of dual sine to the total signal output power to
20%.
Reset status:
50%

[:SOURce]:LFOutput:NOISe <Mode>
Function:
This command is used for setting signal output types when LF Waveform is set to White
noise, which includes: While noise and Gauss. For setting LF waveform, see the
command ―
:LFOutput:SHAPe
‖.
Setting format:
[:SOURce]:LFOutput: NOISe UNIForm|GAUSsian
Query format:
[:SOURce]:LFOutput: NOISe?
Parameter:
<Mode> Discrete data. Options for type of LF noise signal are:
UNIForm White noise,
GAUSsian Gauss.
Example:
:LFOutput: NOISe GAUSsian LF noise is of Gauss type.

[:SOURce]:LFOutput:RAMP <Mode>
Function:
This command is used for setting signal output types when LF Waveform is set as Zigzag,
which include Zigzag-up and Zigzag-down. For setting LF waveform, see the
command ―
:LFOutput:SHAPe
‖.
Setting format:
[:SOURce]:LFOutput:RAMP POSitive|NEGative
Query format:
[:SOURce]:LFOutput:RAMP?
Parameter:
<Mode> Discrete data. Options for type of Zigzag signal are:
POSitive Zigzag-up,
NEGative Zigzag-down.
Example:
:LFOutput:RAMP NEGative LF Zigzag signal is of Zigzag-down type.
Reset status:
