Continuous Sweep Mode

This mode allows you to program the laser to automatically sweep continuously across a user-defined wavelength
range. Click on the Continuous Sweep Mode button to enter this mode. The GUI should appear similar to the image
below. Note that the "Start Sweep" button appears on the right.
The wavelength range can be set by typing the start and stop wavelengths in the boxes at the lower left of the GUI.
Alternately, the start and stop wavelengths can be set by simply dragging the wavelength indicator labels on the
wavelength scale. The sweep speed and number of cycles to sweep can also be specified at the bottom of the GUI.
Similar to the Stepped Sweep Mode, you can select whether the number of sweeps is a fixed number or infinite. In
this image, it shows the "Infinite" selection.
Once the parameters are set, the sweeps are initiated by clicking the Start button. To stop or reset the sweep
function, simply click on the Stop Sweep button that appears. The sweeping will stop, and the laser will return to
the start wavelength.
See the Trigger and Synchronization sections for more information about how to synchronize external equipment
with the TLX3 in the Continuous Sweep Mode.
Note that the Power readout will be blanked during this sweep mode because it's changing too rapidly to be read
accurately.
