LQ-401CL
15
The exposure time is normally the same as the cycle time (in No-shutter mode). By using the
Exposure Control Gate (in Shutter-Select or Pulse Width Control trigger modes) the exposure time
can be individually set to be shorter than the cycle time (the inverse of line rate). This also allows
a fixed exposure time, independent of the line rate. In the LQ-401CL the exposure time can be set
individually for all four channels.
