    Power Requirements

    Table 35. Power Requirements
    Voltage (VDC)Typical Current (A)
    +3.33.3
    +126.0
    Power is 83 W, typical. Consumption is from both PXI Express backplane power connectors. Conditions: Simultaneous generation and acquisition using NI-RFSG and NI-RFSA at 1.25 GS/s I/Q rate, 45 °C ambient temperature. Power consumption depends on FPGA image being used.
