Response: None
Example: :sour0:wav:swe:stop 1550nm
Affects: All N777xC tunable laser sources
Command: :SOURce0:WAVelength:SWEep:STOP?
Syntax: :SOURce0:WAVelength:SWEep:STOP?[<wsp>MIN|MAX]
Description: Returns the end point of the sweep.
Parameters: optional
Response: The wavelength at which the sweep ends as a float value in meters.
Example: :sour0:wav:swe:stop?
Affects: All tunable laser modules
Command: :SOURce0:WAVelength:SWEep:[STATe]
Syntax: :SOURce0:WAVelength:SWEep:[STATe]<wsp>STOP|0|STARt|1|PAUSe|2|CONTinue|3
Description: Stops, starts, pauses or continues a wavelength sweep.
Parameters: 0 or STOP:
1 or STARt:
2 or PAUSe:
3 or CONTinue:
If you enable lambda logging (see
(see
Generally, a continuous sweep can only be started if:
the trigger frequency, derived from the sweep speed and sweep step, is <=1MHz
the number of triggers, calculated from the sweep span and sweep span, is <=1048576
the start wavelength is less than the stop wavelength.
In addition, a continuous sweep with lambda logging requires:
the trigger output to be set to step finished modulation set to off.

MIN Returns the minimum start wavelength available.
This value is sweep speed dependent.
MAX Returns the maximum start wavelength available.
This value is sweep speed dependent.
