Introduction
The ACL-8316/12 series DAS cards are high resolution and high performance, data acquisition cards based on the 16-bit PC/ISA Bus architecture. Both ACL-8316 and ACL-8312 share a common architecture and core features making each card ideal for logging and signal analysis applications.
The ACL-8316/12 series features continuous, high speed, gap-free data acquisition under Windows or DOS environments.
An on-board FIFO buffer and 16-bit DMA data transfer allow the acquisition of large amounts of data without losing data.
The channel auto-scanning lets a high speed acquisition in a sequential order to select channel.
