Troubleshooting (DPO7000 Series, MSO70000/C Series, DSA/DPO70000B/C Series)
Ifthereisadis
play on the XVGA port, but not on the LCD, check the power
supply voltages. If the voltages are okay but there is still no display on the LCD,
replace the display assembly (LCD, lamps, and cable).
Booting Into Windows. If the instrument will not start, run the CMOS restore
utility. (See page 4-43, Update/Restore the μATX Board CMOS.)
If the instrument starts, finds the hard disk, but locks up while displaying the
Windows splash screen:
1. Select the Integrated video port using the setup menu.
2. Disable the buses and disconnect the PPC board by installing J111.
3. If the system boots (It will only boot to Windows, the instrument application
will not run) to the external μATX video port, replace the Power Interface
board.
If the Instrument Application Does Not Work. If the instrument starts Windows, but
the instrument application does not work (the DPO Main graphic is displayed),
check the following:
1. The application software.
2. The Acquisition board.
3. The Power Interface board (try removing and reinstalling the Power Interface
board).
4. Did someone exit the a pplication using Task Manager and then try to reenter
the application without rebooting?
5. If the relays click, the acquisition is running.
6. On the Settings tab of the desktop properties, select Advanced and then the
Performance tab. Hardware Acceleration must be set to Full for video merge
to work. If you chang
e the setting, restart.
Instrument Diagnostics
The primary diagnostics for the instrument are accessible through the oscilloscope
application software. Procedures for running these diagnostics are described next.
The Instrument diagnostics check the basic functionality of the acquisition system
at every power on.
The Instrument Diagnostics run after Windows has booted up and run its own set
of system checks. If any failures occur at power on, a pop-up message indicates
that a failur
e h as occurred and provides a choice to go directly to the diagnostic
results window to view the specific failures, or to ignore them and continue
directly into the oscilloscope application.
Several diagnostic tests are available. (See Table 4-9 on page 4-25.) The table
indicates which tests run automatically at power-up, and which tests are run
manually.
