:SOURce[:MOD]:ASKey Commands
[:SOURce[]][:MOD]:ASKey:AMPLitude
Syntax [:SOURce[]][:MOD]:ASKey:AMPLitude {|MINimum|MAXimum}
[:SOURce[]][:MOD]:ASKey:AMPLitude? [MINimum|MAXimum]
Description Set the ASK modulation amplitude of the specified channel.
Query the ASK modulation amplitude of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real 0Vpp to 10Vpp (HighZ) 2Vpp
Explanation  In ASK modulation, the signal generator shifts its output amplitude between
two preset amplitudes (the carrier amplitude and modulation amplitude).
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the ASK modulation amplitude in scientific notation with 7
effective digits, for example, 1.000000E+00 (the ASK modulation amplitude is
1Vpp).
Example :SOUR1:ASK:AMPL 1 /*Set the ASK modulation amplitude of CH1 to 1Vpp*/
:SOUR1:ASK:AMPL? /*Query the ASK modulation amplitude of CH1 and the
query returns 1.000000E+00*/
[:SOURce[]][:MOD]:ASKey:INTernal[:RATE]
Syntax [:SOURce[]][:MOD]:ASKey:INTernal[:RATE]
{|MINimum|MAXimum}
[:SOURce[]][:MOD]:ASKey:INTernal[:RATE]? [MINimum|MAXimum]
Description Set the ASK modulation rate of the specified channel.
Query the ASK modulation rate of the specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Real 2mHz to 1MHz 100Hz
Explanation  This command is only applicable to the internal modulation source. The ASK
modulation rate refers to the frequency at which the output amplitude “shifts”
between the carrier amplitude and modulation amplitude.
 When [:SOURce[]] or [] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the ASK modulation rate in scientific notation with 7 effective
digits, for example, 1.500000E+02 (the ASK modulation rate is 150Hz).
Example :SOUR1:ASK:INT 150 /*Set the ASK modulation rate of CH1 to 150Hz*/
:SOUR1:ASK:INT? /*Query the ASK modulation rate of CH1 and the query
returns 1.500000E+02*/
