This guide describes how to install and use your SCXI-1305 AC/DC
coupling BNC terminal block.
The SCXI-1305 terminal block is a shielded card with BNC and SMB
connectors that you can connect to the SCXI-1140, SCXI-1141,
SCXI-1120, SCXI-1121, or SCXI-1126 input connectors. You can
configure each SCXI-1305 channel to AC- or DC-couple a signal to an
SCXI module. Each channel can ground-reference a floating signal with a
bias resistor.
The terminal block has eight BNC and one SMB connector for easy
connection. The eight BNCs are for signal connections to the eight module
inputs. The SMB provides access to module digital signals, HOLDTRIG
for the SCXI-1140, and OUTCLK and EXTCLK for the SCXI-1141. These
signals are not active on the SCXI-1120, SCXI-1121, and SCXI-1126.
