Use the source table and the Ramp/Set section to control the amplitude,
phase angle, and frequency of each source. These capabilities enable
the pickup, dropout, and time tests.
Sources to Change
The Ramp/Set section has eight checkboxes, one for each source. To
change the selected variable (amplitude, phase angle, or frequency) for a
given source, click the checkbox for that source.

To avoid altering the values for a source during a test, make sure the
checkbox for that source is not selected.
