:SOURce:SUM Commands
[:SOURce[]]:SUM:AMPLitude
Syntax [:SOURce[]]:SUM:AMPLitude {|MINimum|MAXimum}
[:SOURce[]]:SUM:AMPLitude? [MINimum|MAXimum]
Description Set the sum ratio of the waveform summing function of the specified channel.
Query the sum ratio of the waveform summing function of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real 0% to 100% 10%
Explanation  The sum ratio refers to the ratio that the amplitude of the waveform to be
summed on the basic waveform relative to that of the basic waveform.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the sum ratio in scientific notation with 7 effective digits, for
example, 1.000000E+01 (the sum ratio is 10%).
Example :SOUR1:SUM:AMPL 10 /*Set the sum ratio of the waveform summing function of
CH1 to 10%*/
:SOUR1:SUM:AMPL? /*Query the sum ratio of the waveform summing function
of CH1 and the query returns 1.000000E+01*/
[:SOURce[]]:SUM:INTernal:FREQuency
Syntax [:SOURce[]]:SUM:INTernal:FREQuency {|MAXimum|MINimum}
[:SOURce[]]:SUM:INTernal:FREQuency? [MINimum|MAXimum]
Description Set the sum frequency of the waveform summing function of the specified channel.
Query the sum frequency of the waveform summing function of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real 1uHz to 60MHz 1kHz
Explanation  The sum frequency refers to the frequency of waveform to be summed on the
basic waveform.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the sum frequency in scientific notation with 7 effective digits, for
example, 1.000000E+02 (the sum frequency is 100Hz).
Example :SOUR1:SUM:INT:FREQ 100 /*Set the sum frequency of the waveform summing
function of CH1 to 100Hz*/
:SOUR1:SUM:INT:FREQ? /*Query the sum frequency of the waveform
summing function of CH1 and the query returns
1.000000E+02*/
