3.9 Setting Line Rate and Exposure Mode
The camera’s line rate (synchronization) is generated internally or input from a frame
grabber/host system. With six different exposure mode settings, the Spyder2 delivers
many possibilities for flexible camera timing. Table 5 outlines each of these six exposure
modes, and is followed by a full explanation on how to set the camera’s frame rate and
exposure time.

Overview: Setting Line Rate and Exposure Time
The camera’s line rate (synchronization) can be generated internally through software
commands or input externally from a frame grabber/host system. To select how you
want the camera’s line rate to be generated:
1. You must first set the camera mode using the
sem
command. Refer to Setting the
Exposure Mode on the following page for details.
2. Then, when applicable, use the commands
ssf
(mode 2 only) to set the line rate
and/or
set
(mode 2 or 6), to set the exposure time. Refer to Setting Line Rate and
Setting Exposure Time below for details.
