Hardware Overview
This chapter describes the features of the IMAQ PCI-1410 device and
includes information about acquisition modes, analog front-end
considerations, and clamping.
Functional Overview
The IMAQ 1410 features a flexible, high-speed data path optimized for the
acquisition and formatting of video data from analog cameras. The
IMAQ 1410 can acquire from RS-170/NTSC, CCIR/PAL, VGA, and
progressive scan cameras, as well as from non-standard cameras such as
line scan cameras. The IMAQ 1410 digitizes analog video signals to
8 or 10 bits of resolution at sampling frequencies up to 40 MHz.
The IMAQ 1410 has a factory-calibrated gain circuit to improve
measurement accuracy and board-to-board consistency. It uses a PCI
interface for high-speed data transfer, 16 MB of SDRAM for data
buffering, and region-of-interest control circuitry for optimizing the data
transfer. The 16 MB of SDRAM also allows you to acquire entire images
into onboard memory when necessary. The IMAQ 1410 includes
four external triggers, four camera control signals, seven RTSI bus triggers,
and four video synchronization signals.
