The high-speed analog input channels are single-ended, with hardware programmable input ranges of ±1 V and ±5 V, and input impedances of 50 Ω, 1.25 kΩ and 15 MΩ. The onboard 32 k-sample A/D FIFO can buffer so data throughput is less than 100 Mbytes/s; the FIFO performs as the temporary A/D sample buffer, so no data loss will occur. When four channels operate at 20 MS/s simultaneously, each sample generates two bytes, resulting in 160 Mbytes/s (4 channels \* 20 M \* 2 bytes) of throughput, which exceeds the peak 132 Mbytes/s bandwidth of the PCI bus. To avoid data loss, the FIFO has a 32 k-sample count limitation. In addition to the onboard 40 MHz timebase, users are able to supply an external timebase in either sine wave or digital forms. The PCI-9812 also features an external digital trigger and programmable analog trigger, so the conversion start point of multiple cards can be synchronized to external events. The trigger modes (software-trigger, pre-trigger, post-trigger, middle-trigger and delay trigger) further expand the capabilities of these high-speed devices. ADLINK’s PCI-9812 delivers cost-effective and reliable data acquisition capabilities and is ideal for vibration testing, image digitizing, ultrasonic measurement, biomedical research, ATE and other high-end industrial, scientific, and military applications.
