Boot Up and Initialization
Potential Problems During Boot Process
Initializations Did Not Complete
During the initialization of the MXE EMI Receiver Application the following
messages will be displayed on the application splash screen:
— Checking for required services (1 of 7)
— Initializing License Services (2 of 7)
— Initializing Message Services (3 of 7)
— Initializing Hardware (4 of 7)
— Initializing Data Services (5 of 7)
— Initializing SCPI Services (6 of 7)
— Initializing Front Panel EEPROM Services (7 of 7)
If there is a problem with any of these initializations not completing or causing
an error message to be displayed refer to the instrument Event Log. This can
be accessed by using an external USB keyboard and mouse and selecting
Start, Run, enter Eventvwr.exe, and select OK.
Once the Event Viewer comes up, look under SA for the latest error entries.
Double-click on the entries to view further details, which should give you some
idea of what the problem is.
Fails an Initial Alignment
Troubleshooting Alignment Failures Using the Alignment History
Screen
At instrument power on, an initial alignment is automatically performed. It is
also possible to manually trigger an alignment by pressing System,
Alignments, Align Now, All. The power on alignment performs a few more
alignments than the manual Align Now All routine.
The number of alignments depends on the hardware options present in the
instrument.
Using an external USB keyboard and mouse, access the alignment history,
which can be found in a text file at:
E:AlignDataStorage\AlignmentHistory.txt
You will find the most current alignment information at the bottom of this file.
Look for the failed alignments. From the windows task bar you can select Edit,
Find and type in FAILED and search for a failure.
Note that the information in the history file usually shows that multiple
measurements are made for a given alignment routine, and measured values
with upper and lower limits are given. For example, the Mechanical Attenuator
Algorithm measures and displays all of the attenuator step values. In this case,
you can view which steps fail, and by how much. Then based on the input
attenuator drawing on the MXE RF Block Diagram, you can determine which
