DAS System User Manual
Notes System
On-line documentation provided with the software. This information is
provided in the form of brief, quick-access notes. Two types of notes are
available: Field Notes and Key Notes.
Overlay
A temporary display that partially covers the currently displayed menu;
usually opened by selecting a function key.
Paged Memory
Acquisition memory can be divided into pages, with each page containing a
given number of samples. Allows you to make multiple acquisitions around
the trigger within a single acquisition memory.
Pattern Generator
A module that outputs binary data at specified time intervals. There are both
16- and 32-channel pattern generation modules. (See also 92S16 and 92S32.)
Pipeline
The several stages of latches that acquired data must be clocked through to
reach acquisition memory.
Pod
A fixed group of pattern generator data channels. (See also Pod Connector.)
Pod Clock
Each P6464 and P6465 pattern generator probe provides nine data channels
and one pod clock line. The pod clock is asserted for each pattern generator
clock cycle. The leading edge of the pod clock signal can be delayed 5 ns
relative to the master clock signal; the pulse width is approximately 8 ns.
Pod Connector
A multipin connector that receives data acquisition and pattern generation
probes. Pod connectors form the physical connection between the logic
analyzer and each probe.
Pod ID
A number that identifies the location of each probe (slot number plus pod
letter; for example: 2B). Each probe contains a button that, when pushed,
causes the Pod ID for that probe to appear on the screen.
Podlet
A circuit contained in a flex lead and attached to a probe that provides
square-pin connections to the circuit under test for one data acquisition
channel (or one pattern generation channel) and a ground pin.
