Sequencing Digital Waveforms
The
sequencer
unit
is
a
programmable
finite
state
machine
with
a
microcode
memory
that,
combined
with
the
vector/command
memory,
can
generate
very
long
digital
patters
and
control
signals
at
a
very
high
speed
(up
to
125
MHz).
You
can
select
which
digital
waveforms
from
the
Waveform
list
are
to
be
generated
by
the
Pattern
Generator.
You
can
also
select
their
repetitions
and
duration
and
operations
for
execution
by
the
sequencer
microcode
memory.
You
can
add/remove
waveforms/operations
to
the
Sequencer
with
the
commands
previously
mentioned
in
Sequencing
Analog
Waveforms
(on
page
65)
Note
:
the
Memory
Usage
indicator
visualizes
in
real
time
the
occupation
of
the
hardware
resources.
Signal Definitions
Use
the
following
steps
to
create
a
new
signal
definition.
1.
Double
click
Signal
Definition
on
the
Device
Control
Tree.
2.
The
Signal
Definition
screen
is
shown.
Use
the
Signal
Definition
panel
to
define
a
list
of
signals
or
buses
and
choose
their
correspondence
to
the
channels
of
the
ArbStudio
1102D/1104D
Digital
Pattern
Generator.
Only
the
signals
defined
in
this
panel
can
be
viewed
in
the
Editing
waveform
window
or
Waveform
View
window.
