ARB
(cant)
The resolution (minimum end voltage step) is:
Amplitude (Vp-p)
Resolution
=
.0008
* V LEN *
2
The
voltage
change can range
from
0%
(V HGT = 0)
to
80%
(V
HGT
=
1999)
of
the
peak
to
peak amplitude setting in
.04%
steps,
when
V LEN = 1.
It
is
best
to
keep V LEN as small as possible. This reduces
the
number
of
discrete steps
the
3314A
must
make
to
record the
waveform
and improves resolution. Also,
if
total
V LEN
for
a
waveform
is very great,
the
waveform
may
drift
appreciably.
Vector
Length.
The
length
of
a
vector
in
time
is determined by d t (the
unit
length
of
every
vector) and V
LEN (variable
from
1
to
127
for
each vector). To determine each
vector's
time,
multiply
its
V LEN by d t.
Vector
Marker,.
The
Vector
Marker points
to
a single
vector
(called
the
current
vector).
The
marker
indicates
the
vector
available
for
V HGT and V
LEN
modification
and
inten-
sified
by
the
Z
Axis
output.
Pressing V
HGT
or V
LEN
twice
increments
the
Vector
Marker.
This
feature is useful
for
quick
reviews
or edits
of
an ARB
wave.
