Feature

  • By synchronizing the DMM (digital multimeter) module and the multiplexer module, it realizes a highly accurate and compact scanning system.
    PXI-2530: Can be used as a 1 × 128 channel to 4 × 32 channel multiplexer.
  • Increase PXI-4070 and parallel measurement ⇒ Reduce tact time Increase the number of PXI-2530 to make it multi-channel ⇒ Can be customized as necessary for large scale board.
