Chapter 5: Operation
Once the PIXIS-XF system has been set up, camera operation is basically
straightforward. In most applications you simply establish optimum performance using
the Focus mode (e.g., in WinX/32,) set the target detector temperature, wait until the
temperature has stabilized at the set temperature and then do actual data acquisition in
the Acquire mode. Additional considerations regarding experiment setup and
equipment configuration are addressed in the software manual.
During data acquisition, the CCD array is exposed to a source and charge accumulates
in the pixels. After the defined exposure time, the accumulated signal is readout of the
array, digitized, and then transferred to the host computer. Upon data transfer, the data
is displayed and/or stored via the application software. This sequence is illustrated by
the block diagram shown in
Figure 5-1 .

Whether or not the data are displayed and/or stored depends on the data collection
operation that has been selected in the application software.
