4. Troubleshooting
NOTE If a message of "Will Shut Down in Five Seconds" is displayed in place of "Initializing.."
and the shutdown occurs, the A21 PCI DSP card fails in starting up. The following
message may be displayed before the shutdown occurs:
"Fatal Error: Failed to Initialize DSP Driver":
or "Fatal Error: Failed to Initialize DSP":
This message indicates that the A21 PCI DSP card doesn't work or is not properly
connected to the A20 digital motherboard.
"Fatal Error: Failed to Update DSP Code":
If this happened, the A21 board failed in writing DSP program into flash ROM when the
firmware was installed first or updated to the newest version. A problem in the A21 or A20
is suspected.
Step 4. Power-on self test
The power-on self test is executed once automatically before the measurement starts.
While the power-on self test is in progress, "Executing power on test" is displayed. If the
power-on test fails, an error message is displayed at the left in the instrument status bar. For
more details, refer to “Troubleshooting Using Service Function” on page 64.
Step 5. Measurement view
The measurement view as shown in Figure 4-7 is displayed after the system initialization is
completed without problem.
