The Alta Analog Frame Grabber

The Alta-AN is an affordable, versatile analog product family for Semiconductor and Industrial Vision OEMs. This family can acquire from almost any analog cameras on the market, from high speed asynchronous-reset monochrome cameras to super high resolution color HDTV cameras. The Alta frame grabbers are high-quality, flexible, PCI Express bus imaging products, well supported by an easy-to-use SDK, and drivers for most popular software imaging packages.

There are three main models in the Alta family: Alta-AN1, Alta-AN2 and Alta-AN4. The AltaAN1 has one Virtual Frame Grabber (VFG) and can support one analog camera of any type. The Alta-AN2 has two VFGs and support two cameras, and the Alta-AN4 has four VFGs and support four cameras. Each VFG is a completely independent frame grabber. This means that each VFG can be configured for a different camera, different triggering mode, different destination buffer and can be in a different acquisition state than the other VFGs. But most importantly, all of the VFGs on one board can acquire simultaneously, at the cameras full frame rate and resolution. Each Alta model is a half size x4 PCI Express board (supporting total data rate up to 1.0 GB/S)
