  • High-density Multiplexing/Scanning (1x768 in a VXI Double-slot)
  • High Voltage and Current Carrying Capabilities
  • Extensive Signal Shielding Employed on PCBs for Excellent Signal Fidelity
  • Break-Before-Make (BBM) and Make-Before-Break (MBB) Accomplished in Hardware, Considerably Improving Scanning time

    The SMP3002 high-density multiplexer module is designed for scanning of multiple points to a common bus, either synchronously with an instrument (i.e., using triggers), or asynchronously with individual relay control.

    Up to 768, 1-wire channels can be accommodated in a double-slot VXIbus card (SMP1200) for maximum density, or mixed and matched with other SMIPII™ cards for flexibility. Applications include cable harness testing, semiconductor and PCB testing, or applications where multiple points need to be switched to a common resource. All relays also have individual relay control, and each path allows for 2A switching.

    The SMP3002 consists of 16 individual (1x8) 1-wire multiplexers. All relays are also driven from the VXIbus +5V supply line, since VXIbus mainframes always have ample current capacity on this supply line, as opposed to the +24V or +12V supply lines.
