PCIe-9814
1 Introduction
The ADLINK PCIe-9814 is a 4-channel, 12-bit, 80MS/s PCI
Express digitizer providing speedy, high quality data acquisition.
Each of the four input channels supports up to 80MS/s sampling,
with12-bit resolution A/D converter. 40MHz bandwidth analog
input with 50Ω impedance receives ±0.5V, ±1V, ±5V, and ±10V
high speed signals, and a simplified front end and highly stable
onboard reference provide both highly accurate measurement
results and high dynamic performance.
The PCIe-9814, based on x4 lane slot PCI Express technology,
can be used in any standard PCI Express slot, x4, x8, or x16. With
a PCI Express bus interface and extremely large onboard memory
(up to 1GB), the PCIe-9814 easily manages simultaneous 4-CH
data streaming even at the highest sampling rates.
The PCIe-9814 is auto-calibrated with an onboard reference cir-
cuit calibrating offset and acquiring analog input errors. Following
auto-calibration, the calibration constant is stored in EEPROM,
such that these values can be loaded and used as needed by the
board. There is no requirement to calibrate the module manually.
