To create a *.mdb file to save the test curve 

z

 

If it is blank, the system saves the test curve into the default 
file under the default directory. 

Text FileName 

z

 

To create a *.txt file to save the test data 

z

 

If it is blank, the system will not save the data. 

 

4)  Set parameters in the dialog box.  
5) Click 

OK. A monitor window is displayed showing the CPU/DSP occupancy curve. 

6)  Stop the test in either way below: 

z

 

Close the monitor window.

Right-click the task in the task list below the graphical area. Then click Delete 
Task on the shortcut menu.  

1)  Analysis of CPU occupancy test results  

z

 

When the NodeB works well without carrying services, the CPU occupancy of all 
boards shall stay between 5% and 10%.  

z

 

The CPU occupancy increases when the NodeB carries services. The occupancy 
of all boards shall be smaller than 75%. The system reports alarms if the 
occupancy is greater than 75%.  

z

 

It is normal for the CPU occupancy to stay at 100% for a few seconds. However, if 
the CPU occupancy stays at 100% for more than one minute while the NodeB 
does not carry services, the CPU is faulty.  

2)  Analysis of DSP occupancy test results  

None. 

 

z

 

You can open and query the text file that saves the CPU/DSP occupancy test 
results.  

z

 

The corresponding board is presented at the beginning of the file. The occupancy of 
all CPUs and DSPs under test at one time are recorded in one row with the test time.  

 

The cell service resource query shows the use of service resources of the cell in real 
time. It includes:
