Waveform Utilities
Press I/Q->ARB->Waveform Utilities to enter the waveform utilities setting menu.
Select Segment
Select the waveform segment for scaling or peak clipping the I and Q data.
Scaling
Set the amplitude scaling percentage of a waveform segment.
The signal generator uses an interpolation algorithm (sampling between the I/Q data
points) when reconstructing a waveform. For common waveforms, this interpolation
can cause overshoots, which may create a DAC over-range error condition. This chapter
describes how DAC over–range errors occur and how you can use waveform scaling to
eliminate these errors.
Although scaling maintains the basic shape of the waveform, excessive scaling can
compromise waveform integrity. For example, if the bit resolution becomes too low the
waveform becomes corrupted with quantization noise. To achieve maximum accuracy
and optimize dynamic range, scale the waveform no more than is required to remove
the DAC over-range error.
