Manual Conventions
This manual uses certain conventions that you should be familiar with before
attempting service.
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 adjust-
ment, 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 instru-
ment. 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.
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.
