Troubleshooting

Booting into Windows

If the instrument will not boot, insert the OS Restore DVD and select the Repair
option. After it

fi

nishes, remove the DVD and reboot.

If the instrument still will not boot, contact your nearest Tektronix Service Center.
For contact information, see

Contacting Tektronix

at the front of this manual.

PPC and ATX PC Diagnostics

The primary diagnostics for the instrument are the power-on diagnostics and the
instrument diagnostics, as described in the following paragraphs.

Power-On Diagnostics

The power-on diagnostics check the basic functionality of the instrument at every
power on. If any failures occur at power on, the screen displays the calibration
and diagnostics property page.

The power-on tests verify that hardware is installed and can be accessed by the
software. The tests provide limited diagnostic information. They do not provide
any performance information.

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.

Instrument Diagnostics

The instrument diagnostics provide more extensive tests than the power-on
diagnostics. The instrument executes a set of internal diagnostics at every
power-up. The results can be viewed from the Utilities > Diagnostics dialog.
