Sweep
The Sweep function lets you select between the Triggered and Free Run
modes.
In Triggered mode, the instrument displays data only after all of the trigger
conditions are met. The Triggered mode keeps the instrument from triggering
and displaying data on the screen before a specic trigger event occurs.Each
time the instrument triggers, it lights the Triggered LED. Then, the trigger
circuit is rearmed for the next trigger event.
In Free
Run mode
the
instrument
is
forced
to
trigger
when
armed,
giving
you
glimpses of
the signal,
which
then
allows
you
to
set
up
channel
vertical
scales
to display
signals
.

Source
The
Source
function
displays
a
list
of
the
available
trigger
sources
.
The
list
of
available
trigger
sources
depends
on
the
combination
of
plug-ins
you
are
using.
Changing trigger sources while the instrument is running causes newly
acquired data to overwrite existing waveforms that are on the display.
However, if the instrument is stopped, changing trigger sources does not
change
the
display
until
the
instrument
starts
running
again.
