PXI/DAQ/DAQe-2500 Series
4/8-CH 12-Bit 1 MS/s Analog Output Multi-Function DAQ Cards
Introduction
ADLINK’s PXI/DAQ/DAQe-2500 series are high-speed and high-performance analog output
multi-function DAQ cards able to update up to 8-CH, 12-bit analog outputs simultane-
ously while sustaining a 1 MS/s rate. The reference sources and the output polarities
are programmable on a per channel basis. Combined with a multiplying DAC architecture,
the ADLINK PXI/DAQ/DAQe-2500 series of DAQ cards can generate complex modulated
analog signals.
DAQ-2502
The hardware-based arbitrary waveform generation reduces CPU loading even when all
analog outputs are updating at full speed, and the lengths of waveforms are only limited by
the system memory.
DAQe-2502
The PXI/DAQ/DAQe-2500 series integrates up to 8-CH, 400 kS/s, 14-bit single-ended analog
inputs with programmable polarity, 24-CH programmable digital I/O lines, and a 2-CH 16-bit
general-purpose timer/counter.
PXI-2502
The PXI/DAQ/DAQe-2500 series is able to perform analog input and output functions at
full speed simultaneously and multiple cards can be synchronized through the SSI (System
Synchronization Interface) bus or PXI trigger bus. The auto-calibration functions adjust the
gain and offset to within specified accuracies such that you do not have to adjust trimpots to
calibrate the boards.
