Glossary
single timebase in its operation.
Modules can have from one to five
cards functioning as a single
instrument. When a module has more
than one card, system window will
show the instrument icon in the slot
of the master card.
monitor When using the Emulation
Control Interface, running the
monitor means the processor is in
debug mode (that is, executing the
debug exception) instead of
executing the user program.
OSI Reference Model The Open
System Interconnection Reference
Model is an ISO standard for
worldwide communications that
defines a networking framework for
implementing protocols in seven
layers. Control is passed from one
layer to the next, starting at the
application layer in one station,
proceeding to the bottom (physical)
layer, over the channel to the next
station, and back up the hierarchy.
Logic analyzers typically capture data
at the physical layer or MAC layer.
packet A piece of a message
transmitted over a packet-switching
network, switch fabric, or
multiplexed with other packets (like
in an MPEG-2 transport stream). A
packet has a header which identifies
the packet and a payload which
contains the actual data. Packets are
also sometimes called cells.
packetized data Data that has
been broken down into smaller pieces
for transmission over a packet-
switching network or switch fabric, or
for multiplexing with other data
streams (like in an MPEG-2 transport
stream).
panning The action of moving the
waveform along the timebase by
varying the delay value in the Delay
field. This action allows you to
control the portion of acquisition
memory that will be displayed on the
screen.
pattern mode In an oscilloscope,
the trigger mode that allows you to
set the oscilloscope to trigger on a
specified combination of input signal
levels.
pattern terms Logic analyzer
resources that represent single states
to be found on labeled sets of bits; for
example, an address on the address
bus or a status on the status lines.
period (.) See edge terms, glitch,
labels, and don't care.
physical layer The first layer of the
OSI Reference Model which manages
placing data on and taking data off
