Exposure Modes in Detail Mode 2: Internally Programmable Line Rate and Exposure Time (Factory Setting) Mode 2 operates at a maximum line rate and exposure time. • When setting the line rate (using the 27Hssf command), exposure time will be reduced, if necessary, to accommodate the new line rate. The exposure time will always be set to the maximum time (line period – line transfer time – pixel reset time) for that line rate when a new line rate requiring reduced exposure time is entered. • When setting the exposure time (using the 28Hset command), line time will be increased, if necessary, to accommodate the exposure time. Under this condition, the line time will equal the exposure time + line transfer time.

Spyder 3 GigE User’s Manual 59 Mode 3: External Trigger with Maximum Exposure Line rate is set by the period of the external trigger pulses. The falling edge of the external trigger marks the beginning of the exposure. Example 2: Line Rate is set by External Trigger Pulses. Line Period Line Period Readout Readout EXSYNC Exposure Time Exposure Time Falling Edge Ignored During Readou t Mode 4: Smart EXSYNC, External Line Rate and Exposure Time Falling Edge Ignored During Readout In this mode, EXSYNC sets both the line period and the exposure time. The rising edge of EXSYNC marks the beginning of the exposure and the falling edge initiates readout. Example 3: Trigger Period is Repetitive and Greater than Read Out Time. Line Period Readout Line Period Readout EXSYNC CR=Charge Reset EXSYNC Falling Edge ignored during readout EXSYNC Falling Edge ignored during readout Mode 5: External Line Rate (EXSYNC) and External Pixel Reset (PRIN) In this mode, the falling edge of EXSYNC sets the line period and the rising edge of PRIN sets the start of exposure time.

Exposure Modes in Detail<br />

Mode 2: Internally Programmable <strong>Line</strong> Rate and Exposure Time (Factory Setting)<br />

Mode 2 operates at a maximum line rate and exposure time.<br />

• When setting the line rate (using the 27Hssf command), exposure time will be reduced,<br />

if necessary, to accommodate the new line rate. The exposure time will always be set<br />

to the maximum time (line period – line transfer time – pixel reset time) for that line<br />

rate when a new line rate requiring reduced exposure time is entered.<br />

• When setting the exposure time (using the 28Hset command), line time will be<br />

increased, if necessary, to accommodate the exposure time. Under this condition, the<br />

line time will equal the exposure time + line transfer time.<br />
