Fig.6.1. The X-scaling
control
fields
of
the 2032
Calibration
of
the
X-axis
of
a
trace
displayed on the 2032 Display is defined
by
the X-
scaling
control
fields, (Fig.6.1
),
of
the relevant DISPLAY SETUP. These will
indicate
the
start
value and the
time
or
frequency
span
of
the displayed
trace
or
portion
of
the
trace.
Check
marks
are generated along the
axis
as a visual aid, and
Cursor
read-outs
are in the same units as are defined in the X-scaling fields.
Additional
read-outs
of
X in
user defined engineering units are
available
via
the Flexible Cursor.
6.1.1. Location of Check Marks
on
the X-axis
96
The intervals between check
marks
on the
X-axis
are
fixed
according
to
the displayed
time
or
frequency span, as defined in the X-scaling fields
for
the trace. These intervals
are given in Table 6.1, (time
domain
displays), and Table 6.2,
(frequency
domain
dis-
plays). The
locations
of
the
check
marks
will always be
at
integer
multiples
of
the
corresponding
intervals,
to
the nearest element number. For instance,
display
of
a
50 Hz
frequency
span
starting
at
47,4375
Hz
would
exhibit
check
marks
along the X-
axis at 50, 60,
70,
80, and 90Hz.
