Performing a Sweep Sequence
Generating an Output Trigger Signal During Sweep
In SWEEP mode, the T200S can generate a trigger signal when the laser is sweeping (for
more details on signal levels, see
Technical Specifications
on page 1).
The following figure illustrates the trigger out signal on a one-way sweep:
To activate the output trigger:
1.
In the SWEEP mode window, touch the button.
The mode setting menu appears.
2. In the
Sweep Control
area, select the
Trigger Out
check box.
The icon appears in the Parameters area of the SWEEP window to indicate that
the trigger is activated.
The trigger signal is high when the laser is sweeping the defined wavelength/frequency
range.
When the laser pauses or moves back to the start position, the trigger signal is disabled
(low).
