Glossary
A bit is also a position in a label.
card This refers to a single
instrument intended for use in the
Agilent Technologies 16700A/B-
series mainframes. One card fills one
slot in the mainframe. A module may
comprise a single card or multiple
cards cabled together.
cell The basic unit of transmission in
an ATM network. It is a fixed-size
packet of 53 bytes, made up of 5
header bytes and 48 payload bytes.
channel The entire signal path from
the probe tip, through the cable and
module, up to the label grouping.
click When using a mouse as the
pointing device, to click an item,
position the cursor over the item.
Then quickly press and release the
left mouse button.
clock channel A logic analyzer
channel that can be used to carry the
clock signal. When it is not needed
for clock signals, it can be used as a
data channel, except in the Agilent
Technologies 16517A.
context record A context record is
a small segment of analyzer memory
that stores an event of interest along
with the states that immediately
preceded it and the states that
immediately followed it.
context store If your analyzer can
perform context store
measurements, you will see a button
labeled Context Store under the
Trigger tab. Typical context store
measurements are used to capture
writes to a variable or calls to a
subroutine, along with the activity
preceding and following the events. A
context store measurement divides
analyzer memory into a series of
context records. If you have a 64K
analyzer memory and select a 16-
state context, the analyzer memory is
divided into 4K 16-state context
records. If you have a 64K analyzer
memory and select a 64-state
context, the analyzer memory will be
divided into 1K 64-state records.
count The count function records
periods of time or numbers of state
transactions between states stored in
memory. You can set up the analyzer
count function to count occurrences
of a selected event during the trace,
such as counting how many times a
variable is read between each of the
writes to the variable. The analyzer
can also be set up to count elapsed
time, such as counting the time spent
executing within a particular function
during a run of your target program.
