NI PXI-2584 Signal Connections

Use the two reference (REF) connections of the NI PXI-2584 to lower emissions (noise) and preserve signal integrity. The reference connections of NI PXI-2584 should be electrically connected to each other at all times and used only in 1-wire topologies.

1-Wire Dual 6×1 Multiplexer Topology

The following figures represent the NI PXI-2584 in the 1-wire dual 6×1 multiplexer topology using reference connections. Depending on the reference signals you want to connect, choose one of following configuration options:

• When the reference signals connected to both multiplexers are the same, connect the reference signals to REF, as shown in the following figure.
  
  
• When the reference signals connected to both multiplexers are not the same, connect the reference signals of one multiplexer to REF and the reference signals of the other multiplexer directly to the measurement device, as shown in the following figure.
