4 Measurement Operations & Settings
Lambda logging is disabled at the end of a sweep.
Generally, a continuous sweep can only be started if:
•
•
•
In addition, a continuous sweep with lambda logging requires:
•
•
Parameters: 0 or OFF:
1 or ON:
Response: None
Example: :sour0:wav:swe:llog 1
Affects: All tunable laser modules that support continuous sweep.
Command: :SOURce0:WAVelength:SWEep:LLOGging?
Syntax: :SOURce0:WAVelength:SWEep:LLOGging?
Description: Returns the state of lambda logging.
Parameters: None
Response: A boolean value:
Example: :sour0:wav:swe:llog? -> 1
