National Instruments Corporation 781672-01 PMI 100KHz - 26.5GHz Downconverter for NI Digitizers

The NI 5734 adapter module for NI FlexRIO is a general-purpose digitizer designed to provide flexible measurement capabilities while offering the benefits of hardware customization through a user-programmable FPGA. At 16 bits of resolution, the module delivers extremely high dynamic range over a wide bandwidth to meet a variety of application requirements. Four input channels also deliver unprecedented channel density per PXI slot at this level of performance. Software-selectable AC and DC coupling allow the module to interface to a variety of signal sources. A 2 Vpp input range with a 50 input impedance and 0 dB, 6 dB, or 12 dB of programmable gain provide maximum dynamic range for low-amplitude signals, while external attenuation (not supplied) can allow the module to safely acquire larger voltages. For time-domain applications, a selectable Bessel filter minimizes group delay over the input bandwidth. For frequency-domain applications, an elliptic filter maximizes flat bandwidth. Or, for maximum flexibility, a filter bypass path enables undersampling or external user-customizable input filtering. Twelve bidirectional digital I/O lines also permit digital device under test control and simple digital protocols.
