Section 7: TSP command reference 

 

2600BS-901-01 Rev. B / May 2013 

7-287 

 

In addition to the above constants, 

operationRegister

 can be set to the numeric equivalent of the bit to set. 

For example, to set bit B10, set 

operationRegister

 to 1024. 

Example 

 

status.operation.instrument.trigger_blender.enable = 1024 

 

Uses a decimal value to set 
the TRGOVR bit of the 
operation status trigger 
blender summary enable. 

 

Also see 

Operation Status Registers

 (on page E-9)
