:SOURce:APPLy Commands
[:SOURce[]]:APPLy?
Syntax [:SOURce[]]:APPLy?
Description Query the waveform type as well as the frequency, amplitude, offset and phase of the
specified channel.
Parameter Name Type Range Default
[] Discrete 1|2 1
Explanation  When [:SOURce[]] or [] is omitted, the command queries the related
parameters of CH1 by default.
 The channel waveform types and the corresponding returned waveform names
are as shown in the table below.
Sine
Square Ramp Pulse Noise
Arbitrary Waveform
DC Except DC
SIN
SQU RAMP PULSE NOISE DC USER
Return Format The query returns a string enclosed in double quotation marks. The return value
consists of 5 parts separated by commas; wherein, the first part is the waveform
name of the specified channel and the rest 4 parts are the frequency, amplitude,
offset and phase (in scientific notation form with 7 effective digits and the default
units are Hz, Vpp, V
DC
and ° respectively; the absent item is replaced by DEF) of the
waveform of the specified channel respectively. For example,
"SQU,1.000000E+03,2.000000E+00,3.000000E+00,4.000000E+00" which denotes
that the current waveform is square, the frequency is 1kHz, the amplitude is 2Vpp, the
offset is 3V
DC
and the start phase is 4°.
Example SOUR1:APPL? /*Query the waveform type as well as the frequency, amplitude,
offset and phase of CH1 and the query returns
"SQU,1.000000E+03,2.000000E+00,3.000000E+00,4.000000E+0
