Chapter 2: Nano-XF Camera System
All standard Nano-XF:11000 systems include a multi-head MegaPlus Camera Controller
and an EPIX PIXCI frame grabber board with EPIX XCAP software or a National
Instruments PCIe 1427 frame grabber with NI-IMAQ software.
Nano-XF cameras and controllers contain very low noise, high dynamic range CCD
electronics with 12-bit digitalization. Among the many advantages of the Nano-XF
system are:
• Camera Link digital image output;
• Multiple trigger modes (Modes 0, 1, and 6) including double triggering and
internal triggering;
• Field upgradeable firmware;
• Low dark noise and thermal drift.
The Camera Controller houses the camera imaging electronics, and connects to the
host PC Camera Link. By separating the camera electronics and image handling
software from the CCD, the Nano-XF camera is able to maintain cooler CCD
temperatures and achieve lower noise and higher dynamic range than comparable
cameras. See
Figure 2-1 .

2.1 Features
The following camera features can be controlled via the serial link embedded in the
Camera Link connection. Availability of some features depends on the firmware
configuration of the camera.
• Bit Depth/Bit Window Selection
Enables users to select the bit-depth of data output from the camera. All
internal data is 12 bits per image. When bit depths less than 12 bits are selected,
the least significant bit can be specified in order to select which of the 12
available bits is output, creating a bit window.
• Brightness (Offset)
Controls the black level or offset of the image by specifying a digital number to
be added to all image pixel data. This value can be written to and read from the
camera.
