AM:STATe {OFF|ON}
Disable or Enable the amplitude modulation. The default is OFF.
To avoid multiple waveform changes, you can enable AM after setting the
modulation parameters.
AM:STATe?
“0” (OFF) or ”1” (ON) will be returned.
APPLy:
SINusoid [<frequency> [,<amplitude > [,<offset>] ]]
Output a sine wave with specific frequency, amplitude and offset. The waveform
is output as soon as the command is executed.
APPLy:
SQUare [<frequency> [,<amplitude > [,<offset>] ]]
Output a square wave with specific frequency, amplitude and offset. The duty
cycle is set automatically to 50%. The waveform is output as soon as the
command is executed.
APPLY:
RAMP [<frequency> [,<amplitude > [,<offset>] ]]
Output a ramp wave with specific frequency, amplitude and offset. The
symmetry is set automatically to 100%. The waveform is output as soon as the
command is executed.
APPLY:
PULSe [<frequency> [,<amplitude > [,<offset>] ]]
Output a pulse wave with specific frequency, amplitude and offset. The
waveform is output as soon as the command is executed. This command works
with the current edge time setting and the current duty cycle or pulse width
setting, depending on which has been selected to “hold” (FUNC:PULS:HOLD
command). However the waveform generator will adjust the pulse width or the
edge time to comply with the frequency restrictions for pulse waveforms.
APPLY:
NOISe [<frequency︱DEF> [,<amplitude > [,<offset>] ]]
Output Gaussian pulse wave with the specific frequency, amplitude and (dc)
offset. The waveform is outputted as soon as the command is executed. The
specified frequency has no effect on the noise
wave, but is remembered by the
