7.1.1 (c) Programmable Shutter Speed<br />
“Programmable” Shutter Speed is set by entering a number in the “Expo (lines)” text box. Programmable<br />
is available in Continuous or Trigger mode. The Expo setting is used instead of the Scan Area<br />
selection.<br />

To use Programmable shutter speed, select Programmable.<br />
7.1.1 (d) Expo (lines)<br />
The “Expo (lines”) selection of the Exposure Control frame determines how long the shutter remains<br />
open, since a certain amount of time is allotted to expose each line. A minimum of one line of pixels<br />
must be exposed. The maximum number of lines is 2048. Enter the number of lines desired either by<br />
clicking on the arrows in the interface, or by inputting a number directly into the text box beside the<br />
“Expo (lines)” box. The control is inactive unless “Shutter Speed” is set to “Programmable”.<br />
7.1.2 Configuring Trigger Settings<br />
Trigger mode uses a manual or sensor command to control the shutter. The Trigger mode offers several<br />
settings not available in Continuous mode.<br />
7.1.2 (a) Pulse Width Control Mode<br />
Pulse Width Control (PWC) is controlled by the external trigger. An external trigger is used to generate<br />
one discharge signal (Vsub) right after the active edge of the trigger. The exposure starts when<br />
the discharge signal is in the off state. The exposure is off following the trigger active off. Exposure<br />
time is controlled by the pulse width of the external trigger.<br />
