Using Waveform Clipping
Using Waveform Clipping
Clipping limits power peaks in waveform segments by clipping the I and Q data to a selected percentage of
its highest peak. Circular clipping is defined as clipping the composite I/Q data (I and Q data are equally
clipped). Rectangular clipping is defined as independently clipping the I and Q data. For more information,
see “Waveform Clipping Concepts” on page 113.
In this section, you learn how to clip waveform segments. If you have not created waveform
segments, complete the steps in the previous section, “Creating Waveform Segments” on page 100.
To Configure Circular Clipping
1. Press Mode > Dual ARB > Waveform Segments.
2. Press
Load Store to Store.
3. Highlight the first waveform segment (for example, TTONE).
4. Press
Waveform Utilities > Clipping.
5. Press
Clip |I+jQ| To > 80 > % > Apply to Waveform.
The I and Q data are both clipped by 80%. You will see 80.0% displayed below the
Clip |I+jQ| To softkey.
To Configure Rectangular Clipping
1. Press Mode > Dual ARB > Waveform Segments.
2. Press
Load Store to Store.
3. Highlight the second waveform segment (for example, MTONE).
4. Press
Waveform Utilities > Clipping.
5. Press
Clipping Type |I+jQ| |I|,|Q|.
This activates the
Clip |I| To and Clip |Q| To softkeys that allow you to configure rectangular
(independent) I and Q data clipping.
6. Press
Clip |I| To > 80 > %.
7. Press
Clip |Q| To > 40 > % > Apply to Waveform.
The I and Q data are individually clipped by 80% and 40%, respectively. You will see 80.0% displayed
below the
Clip |I| To softkey and 40.0% below the Clip |Q| To softkey.
