1 Introduction
The JYTEK PCIe-69814 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, with 12-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-69814, 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-69814 easily manages simultaneous 4-CH data streaming
even at the highest sampling rates.
The PCIe-69814 is auto-calibrated with an onboard reference circuit 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.
