Notes
• While changing amplitude, you may notice a momentary
disruption in the output waveform at certain voltages due to
switching of the output attenuators. You may use disable the
voltage autoranging to prevent this output disruption.
• With auto-ranging off, the resolution and accuracy of amplitude
and offset may be affected when reducing the amplitude below the
expected range change. And you may not be able to achieve the
minimum amplitude that is available when autoranging is on.
