Installing the SMB-2163 on the PXIe-6571

The SMB-2163 (NI part number 778747-01) is an SMB breakout box for high-speed digital devices. This breakout box connects to other devices for testing and debugging by routing every DIO and control channel on a separate SMB coaxial connector.

Complete the following steps to install the SMB-2163 on a module and prepare signal connections.

Caution Disconnect power from the device, accessory, and any other connected hardware before connecting the cable to prevent damage to the hardware and personal injury. NI is not liable for damage resulting from improper connections.

    Item DDC Pin Signal Description
    1 STROBE Bidirectional digital data channels 0 through 31.
    2 DDC CLK OUT External Sample clock source for pattern acquisition.
    3 DIO <0..31> Exported Sample clock signal.
    4 68-Pin Digital Data & Control (DDC) Connector Programmable function interface channels 1 through 3.
    5 Programmable Function Interface (PFI) <1..3> Ground reference for signals.
    6 Shield Ground Lug These channels are reserved for system use. Do not connect signals to these channels.
    Caution Connections that exceed any of the maximum ratings for the SMB-2163 or the digital pattern instrument can damage the device and the computer. NI is not liable for any damages resulting from such signal connections. Refer to SMB-2163 User Guide at ni.com/docs for details about the maximum input ratings.
    Note To ensure a solid ground connection, tighten the SMB connectors by gently snapping them into place.
    Note For additional shielding, you can connect the shield ground connector on the SMB-2163 to earth/hard ground. This terminal is connected to the shielded enclosure ground.
