Pre-Acquisition Setup - CCD
5.3.1 - Acquisition Modes & Timings
An acquisition is taken to be the complete data capture process that is executed whenever user selects Take Signal,
Take Background, or Take Reference from the acquisition menu, or whenever user clicks the Take Signal button. By
contrast, a scan (an “acquired scan” in the denitions that follow) is a single readout of data from the CCD-chip. Several
scans may be involved in a complete data acquisition. The minimum time required for an acquisition is dependent on
a number of factors, including the exposure time (i.e. the time in seconds during which the CCD collects light prior to
readout) and the triggering mode. Triggering modes are described in more detail later in this section.
5.3.1.1- Single Scan
Single scan is the simplest acquisition mode, in which the system performs one scan of the CCD.
The following parameters can then be changed:
• Exposure Time
Note: Should user attempt to enter too low a value, the system will default to a minimum exposure time.
