Glossary
synchronously with a clock signal in
the target system.
Subnet Mask A subnet mask blocks
out part of an IP address so that the
networking software can determine
whether the destination host is on a
local or remote network. It is usually
represented as decimal numbers
separated by periods; for example,
255.255.255.0.
Symbol Symbols represent patterns
and ranges of values found on labeled
sets of bits. Two kinds of symbols are
available:
1) Object file symbols — Symbols
from your source code, and symbols
generated by your compiler. Object
file symbols may represent global
variables, functions, labels, and
source line numbers.
2) User-defined symbols — Symbols
you create.
Target Board Adapter A daughter
board inside the E5900B emulation
probe which provides an interface to
the ribbon cable for a particular
microprocessor family.
Target Control Port An 8-bit, TTL
port on a logic analysis system that
you can use to send signals to your
target system. It does not function
like a pattern generator or emulation
module, but more like a remote
114
control for the target's switches.
Target Interface Module A small
circuit board which connects the 50-
pin cable from an E5901A emulation
module or E5900A emulation probe
to signals from the debug port on a
target system. Not used with the
E5900B emulation probe.
TIM See Target Interface Module.
Timing Analysis When the logic
analyzer is configured to capture data
at a rate determined by an internal
sample rate clock, asynchronous to
signals in the target system.
Transition Board A board
assembly that obtains signals
connected to one side and rearranges
them in a different order for delivery
at the other side of the board.
Trigger Specification A set of
conditions that must be true before
the instrument triggers. See the
printed or online documentation of
your logic analyzer for details.
1/4-Flexible Adapter An adapter
that obtains one-quarter of the
signals from an elastomeric probe
adapter (one side of a target
microprocessor) and makes them
available for probing.
