Introduction
The ADLINK PCIe-9842 is 200MS/s 14-bit 1-CH digitizer designed
for applications such as LIDAR tests, optical fiber tests and radar
signal acquisition. The 100MHz bandwidth analog input is
designed to receive ±1V high speed signal with 50
Ω
impedance.
With this simplified front-end design and high stable onboard refer-
ence, PCIe-9842 provides not only high accuracy measurement
results but also delivers high dynamic performance.
For applications that require data to be acquired and transferred in
real-time, PCIe-9842 is designed on the PCI Express x4 bus as
the interface. When signal is converted from analog to digital data,
data will be transferred to host system memory continuously due
to PCI Express high bandwidth features.
The auto-calibration function of the PCIe-9842 is performed with
onboard reference circuit that calibrates the offset and gain errors
of analog input. Once the auto-calibration procedure is done, the
calibration constant will be stored in EEPROM such that these val-
ues can be loaded and used as needed by the board. Because all
the calibration is conducted automatically by software commands,
users don’t have to calibrate the module manually.
