Introduction

ADLINK PCI-9812, PCI-9810 and PCI-9812A are 4-CH, 10 or 12-bit, 20 MS/s simultaneous-sampling analog input cards. The high-speed analog input channels are

single-ended, with hardware programmable input ranges of ±1 V, ±5 V and input impedances of 50 Ω, 1.25 kΩ and 1 MΩ. The on-board 32k-sample A/D FIFO can buffer

the sampled data. When the data throughput is less than 100 Mbytes/s, the FIFO performs as the temporary A/D sample buffer, and as a rule of thumb, no data loss will

happen. When four channels operate at 20 MS/s simultaneously, each sample generates two bytes, resulting in 160 Mbyes/s (4 channels* 20M * 2 bytes) throughput,

which exceeds the peak 132 Mbyte/s bandwidth of PCI bus. To avoid data loss, the 32k-sample FIFO is the limitation of sample count. For applications needing a larger

number of samples at full sampling rate, the PCI-9812A features 128K-sample A/D FIFO for storage.

In addition to the on-board 40MHz time base, users are able to supply the external time base in either sine wave or digital forms. The PCI-9810 and PCI-9812 also

feature external digital trigger and programmable analog trigger, thus the conversion start point of multiple cards can be synchronized to external events. The trigger

modes include software-trigger, pre-trigger, post-trigger, middle-trigger and delay trigger, further expands the capabilities of these high-speed devices.

ADLINK PCI-9812, PCI-9810 and 9812A deliver cost-effective and reliable data acquisition capabilities and are ideal for vibration testing, image digitizing, ultrasonic

measurement, biomedical research, ATE and other high-end Industrial/Scientific/Military applications.
