to one second also sets the delay parameter of the
other voltage sweep waveforms to one second.

Changing the '1evel" of a sweep waveform also
changes the "start'' value of the other sweep
waveforms of the selected source. Conversely,
changing the "start'' value also changes the "level"
of the other sweep waveforms for the selected
source.

Cycling power will
not
affect the last created sweep.
If
a sweep
was
run, the data (measurements
and
AT),
will
be
retained
in
the buffer.

Performing factory initialization
will
clear the sweep
buffer. The last created sweep
will
be cancelled.
Sweep
parameters return to the factory default
