PC Interface and PC Motherboard Diagnostics
The primary diagnostics for the oscilloscope are the power-on diagnostics, the
PC diagnostic software, and the oscilloscope diagnostics. Procedures for running
these diagnostics are described below.
The power-on diagnostics check the basic functionality of the oscilloscope at
every power on. If any failures occur at power on, the screen displays the
calibration and diagnostics property page. Table 6--7 lists a subset of the power
on tests. Use the results of the tests to help you isolate problems to system
modules.
The power on tests ensure that hardware is installed and can be accessed by the
software. The tests provide limited diagnostic information, but do not provide
any performance information. The oscilloscope diagnostics provide more
extensive tests than the power-on diagnostics.
The power on tests check the generic hardware including the keyboard, mouse,
memory, CPU, and associated peripherals. The interrupt lines and trigger lines
are also checked.
If there are no failures, you can view the results of the tests in the Instrument
Diagnostics page under the Utilities menu.
