Acquisition Board
Adjustment Procedures
Adjustment/Verification
Fixture
Certification Procedures
Daughter Board
Functional Verification
Procedures
The acquisition board is one of the circuit boards inside the logic analyzer
module. The circuit board receives and stores acquisition data from the probes
and works with the LPU board to provide logic analysis information to the
operator of the logic analyzer.
Adjustment procedures check for, and if necessary, correct any adjustment errors
discovered when performing functional or performance verification procedures.
The adjustment/verification fixture is a test fixture used to perform the adjustment, functional check, and performance verification procedures. Specifications
and replaceable parts information are documented in this service manual.
Certification procedures certify a product and provide a traceability path to
national standards.
The daughter board provides additional channels for the logic analyzer. Data
from these channels is sent to the acquisition board for processing with other
data from the acquisition board.
Functional verification procedures verify the basic functionality of the instrument. These procedures include power-on and extended diagnostics, self
calibration, as well as semi-automated or manual check procedures. These
procedures can be used as incoming inspection purposes. This manual provides
information on power-on and extended diagnostics and the self calibration.

LPU Board
The Local Processor Unit (LPU) Board. The LPU board is one of the circuit
boards inside the logic analyzer module that provides the main communications
interface with the mainframe.

Safety
Maintenance procedures are used for fault isolation and repair to the circuit board
level or to the replaceable part level.
Throughout this manual, the term “module” refers to a logic analyzer or DSO
unit that mounts inside a mainframe. A module is composed of circuit cards,
interconnecting cables, and a user-accessible front panel.
Performance verification procedures confirm that a product meets or exceeds the
performance requirements for each of the published specifications.
This manual refers to any field-replaceable assembly or mechanical part
specifically by its name or generically as a replaceable part. In general, a
replaceable part is any circuit board or assembly, such as the hard disk drive, or a
mechanical part, such as the I/O port connectors, that is listed in the replaceable
parts list.
Symbols and terms related to safety appear in the Safety Summary found at the
beginning of this manual.

H 100 MHz synchronous acquisition with a programmable setup and hold
window (PowerFlex configurable to 200 MHz)
H 250 MHz asynchronous full depth selections with selectable sampling rates
H 2 GHz asynchronous acquisition into a 2 K high resolution timing buffer
H 250 MHz trigger capability, plus special setup and hold violation triggering
and glitch triggering
Characteristic Tables
H Data correlation with other modules
This section lists the specifications for the logic analyzer module. All specifications are guaranteed unless noted Typical. Specifications that are marked with the

contains the most-significant groups.
The master module is to the left (lower-numbered slot) of a merged pair.

is located to t he right of the master module, and slave module 2 is located to the left
of the master modul e.

Table 1- 3: LA module trigger system (Cont.)
Characteristic Description
Storage control
Global storage Storage is allowed only when a specific condition is met. This condition can use any
of the trigger machine resources except for the counter/timers. Storage commands
defined in the current trigger state will override the global storage control.
Global storage can be used to start the acquisition with storage initially turned on
(default) or turned off.
By event Storage can be turned on or off; only the current sample can be stored. The event
storage control overrides any global storage commands.
Block storage When enabled, 31 samples are stored before and after the valid sample.
Block storage is disallowed when glitch storage or setup and hold v iolation is enabled.
Glitch violation storage The acquisition memory can be enabled to store glitch violation information with each
data sample when asynchronous clocking is used. The probe data storage size is
reduced by one half (the other half holds the violation information). The fastest
asynchronous clocking rate is reduced to 10 ns.
1
Each use of a glitch detector, setup and hold violation detector, or transition detector requires a trade-off of one word
recognizer resource.
2
Any glitch is subject to pulse width variation of up to the channel-to-channel skew specification + 0.5 ns.
3
For TLA7N1, TLA7N2, TLA7N3, TLA7N4, TLA7P2, TLA7P4, TLA7Q2, and TLA7Q4 Logic Analyzer modules, any setup
value is subject to variation of up to 1.8 ns; any hold value is subject to variation of up to 1.2 ns.

This mode can be used to create transitional storage selections where all channels are enabled.
