PXIe-9848
1 Introduction
The PXIe-9848 high-speed 8CH 14-bit 100 MS/s digitizer is specif-
ically designed for applications such as PSU (power supply unit)
testing, LIDAR testing, and radar signal acquisition. Analog inputs
with 100 MHz bandwidth can receive ±2V high-speed signals with
50Ω impedance. With a simplified front-end design and highly sta-
ble onboard reference, the PXIe-9848 provides not only highly
accurate measurement results but also superior dynamic perfor-
mance.
For applications requiring real-time data acquisition and transfer,
PXIe-9848 is based on the PXI Express x4 bus interface. When
signals are converted from analog to digital, data is continuously
transferred to host system memory thanks to maximized PCI
Express bandwidth.
PXIe-9848's auto-calibration is performed with onboard reference
circuitry that calibrates the offset and gain errors of analog input.
Once complete, the calibration constant is stored in EEPROM, to
be loaded and used as needed by the board. Because all calibra-
tion is executed automatically by software command, no manual
calibration of the module is required.
