76 Keysight N777xC Series Tunable Laser Family Programming Guide
4 Measurement Operations & Settings
Parameters: The wavelength at which the sweep starts as a float value.
If you specify no units in your command, meters are used as the default.
Also allowed are:
MIN: minimum programmable value
MAX: maximum programmable value
Response: none
Example: :sour0:wav:swe:star 1500nm
Affects: All N777xC tunable laser sources
Command: :SOURce0:WAVelength:SWEep:STARt?
Syntax: :SOURce0:WAVelength:SWEep:STARt?[<wsp>MIN|MAX]
Description: Returns the starting point of the sweep.
Parameters: optional 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.
Response: The wavelength at which the sweep starts as a float value in meters.
Example: :sour0:wav:swe:star? -> +1.50000000E-006
Affects: All N777xC tunable laser sources
Command: :SOURce0:WAVelength:SWEep:STOP
Syntax: :SOURce0:WAVelength:SWEep:STOP<wsp><stop value>[PM|NM|UM|MM|M|MIN|MAX]
Description: Sets the end point of the sweep.
Cannot be set while a sweep is running.
Parameters: The wavelength at which the sweep ends as a float value in meters.
If you specify no units in your command, meters are used as the default.
MIN Sets the minimum stop wavelength available.
This value is sweep speed and mode dependent.
MAX Sets the maximum stop wavelength available.
This value is sweep speed and mode dependent.
