Overhead Delay
Overhead_Delay can range from 5 to 6μs and depends on the internal operations of your computer.
Exposure Controls
The camera can grab images in one of seven ways. The cameras line rate (synchronization) can be
generated internally through the Acquisition Line Rate feature (a member of the Sensor Control set of
features) or set externally with an EXSYNC signal, depending on your mode of operation.
To select how you want the camera’s line rate to be generated:
1. First set the camera mode using Exposure Mode and Line Trigger Mode commands.
2. Next, if using mode 2, 6, or 7 (see below) use the commands Acquisition Line Rate Abs and/ or Exposure
Time Abs to set the line rate and exposure time.
