Probing
This chapter contains a description of the probing system for the logic
analyzer. It also contains the information you need for connecting the
probe system components to each other, to the logic analyzer, and to
the system under test.
Probing Options
You can connect the logic analyzer to your system under test in one of
the following ways:
•
The standard general purpose probing (provided).
•
HP E2445A User-Definable Interface (optional).
•
Direct connection to a 20-pin, 3M-Series type header connector
using the termination adapter (optional).
•
Microprocessor and bus-specific interfaces (optional).
General-Purpose Probing
General-purpose probing involves connecting the logic analyzer
probes directly to your target system without using any interface.
General purpose probing does not limit you to specific hook up
schemes, as for example, the probe interface does. General-purpose
probing uses grabbers that connect to both through hole and surface
mount components.
General-purpose probing is the standard probing option provided with
the logic analyzer. There is a full description of its components and
use later in this chapter.
