ADJUSTMENT PROCEDURES FOR THE 318
INTRODUCTION
The following pages contains the Adjustment Procedures for the 318 Logic Analyzer. Information on the 338 Logic
Analyzer is located later in Section 5; refer to the page-edge tabs for help in locating 338 information.
The following pages contain procedures for adjusting instrument variables so that the instrument meets or exceeds
performance specifications. If the product cannot be made to meet or exceed specifications by following these
procedures, repair is necessary.
IMPORTANT-PLEASE READ BEFORE USING THIS PROCEDURE
PURPOSE
The Adjustment Procedure provides a sequence for adjustments. It is not a troubleshooting guide or a verification
procedure. The Adjustment Procedure is divided into sub-sections that describe adjustments for one particular board or
set of boards in the 318.
LIMITS AND TOLERANCES
All limits and tolerances given in this procedure are adjustment guides. They should not be interpreted as instrument
specifications unless they are also found in the
Specifications
part of this manual.
Tolerances given are for the instrument under test and do not include test equipment error.
EQUIPMENT REQUIRED
The equipment listed at the beginning of this
Adjustment and Verification Procedures
section in Table 5-1 is necessary to
complete all the adjustment procedures. A partial list of equipment needed for each individual check and adjustment is
also shown at the beginning of each procedure’s major step. The equipment specifications given in Table 5-2 are the
minimum necessary to produce accurate results. Therefore, equipment substitution must meet or exceed the listed
specifications. Detailed instructions for operating the test equipment are not offered in this manual. Refer to the manual
for the specific test equipment if more information is required.
EQUIPMENT ALTERNATIVES
When equipment other than recommended test equipment is substituted, control settings or adjustment setups may need
to be altered. If the exact equipment listed in Table 5-1 is not available, check the Minimum Specification column in
Table 5-2 carefully to see if any other equipment will suffice.
ADJUSTMENT INTERVAL
To ensure correct instrument operation, adjustment should be checked every 1000 hours of operation or every six months
if used infrequently. Before performing the adjustment procedures, perform preventive maintenance as outlined in
5-22
