Calibrations
Mainframe
calibration
(performed
at
the
factory)
improves
timebase
accuracy
.
All
timebase
measurements
such
as
rise
time
,
fall
time
,
eye
width,
jitter
,
and
so
forth
are
aected
by
the
timebase
accuracy
.
The
calibration
factors
are
stored
in
the
nonvolatile
RAM
of
the
instrument.
There
is
a
switch
on
the
back
panel
of
the
instrument
that
allows
the
mainframe
calibration
to
be
protected
or
unprotected.
Next
to
the
switch
there
is
a
drawing
that
shows
each
switch's
function
and
protected
position.
Refer
to
the
optional
