5.2  The control windows 

5.2.1  The Operate window 

 

 
In the 

Operate

 window you can change the 

operating mode

, 

wavelength

, 

power

 and 

tuning speed

.   

All white parameters and slides are adjustable (when not grayed out). 
All yellow parameters and slides are indicators. 
The unit of the Wavelength and Power controls can be changed at runtime. This will 
also affect all indicators except for the channel slide indicator. 
 
The status signals are: 
The 

Working

 indicatior in the lower left corner indicates that the software is busy. 

Then all parameters set in the program are stacked in queue and no indicators are 
updated on the screen. 
The 

Pending

 indicator shows if the laser unit is under operation. 

The 

Fatal, ALM 

(alarm)

 

and

 SRQ 

(service request) are signals that indicate that 

something is wrong with the laser.  

CE

 indicates communication error. 

XE

 indicates execution error.
