Switching from "Attenuation Mode" to "Constant Power Mode" will automatically set the current measured 
optical power as the set point. 

 

Note

: The software will provide a warning when you attempt to ‘Set’ values that are not valid or out of the

 

operating range of the VOA channels.

The 

Offset Modes 

parameters tab is used to select the offset mode for attenuation control.
