DIAGNOSTIC TESTS
Introduction
This section contains information for executing the 1260-00C
diagnostic self-tests. The diagnostics test each 1260-00C
subcircuit, and are useful in detecting and isolating problems.
The diagnostics mode can be entered through any of the
following methods.
a. Set the start-up mode switches to the diagnostics mode
as described in Section 3 Start-Up Mode Configuration.
Set switch S19 to the OFF position, and set switch S20 to
the ON position. Restart the system.
b. In VXI pROBE mode (on development modules only),
enter the diagnostic mode through the pROBE
DIAG
command.
c. In 488-VXI runtime system mode, enter the diagnostic
mode through the
DIAG
command.
The diagnostic commands must be executed from the RS-232
port.
Configuration for
Diagnostic Testing
The diagnostic tests require the 1260-00C to be disconnected
from all other GPIB devices to prevent interference with the
GPIB tests.
Diagnostic Test
Structure
A total of 263 diagnostic routines, or tests, are organized in
groups as shown in Table 6-1. Each test is composed of one or
more subroutines called
commands
.
Each test is designed to functionally test a specific part of the
1260-00C circuitry. The diagnostics can be executed by test
groups or by individual tests.
