High Speed Capture Option

If this option is purchased with a Silent Hawk® III, the unit's specifications change. This package allows much faster speeds for each data capture mode of the Silent Hawk®. In Host Strobe Mode, a forward data capture speed of one megabyte per second can be easily sustained. In IEEE-1284 Analysis Mode a capture rate of five hundred kilobytes per second is obtainable. The High Speed Capture Option include a FIFO upgrade that brings the maximum FIFO size to 128 kilobytes from the standard 4 kilobyte buffer.
