PLS LIGHT MEASURE
You can enter pulse light measurement settings and external trigger mode settings.
PEAK HOLD
You can set the peak hold value for the pulse light. Pulse light measurement can be
carried out based on this.
The setting range is 1 to 9999 ms.
EXT TRIGGER MODE
This mode is used to measure pulse light using an external trigger signal. When this key
is selected, sweeping is performed in external trigger mode, wherein sampling is done
based on an external trigger signal.
For information on external trigger measurement, see section 5.15.
Measurement Sensitivity and Corresponding Pulse Width
The measurement sensitivity is determined based on the light pulse width. Select the
appropriate sensitivity level based on the pulse width in the table below.
