Note
Signal names printed in black (the first name in the pair) are for the SCXI-1120/D,
SCXI-1125, SCXI-1126, SCXI-1140, and SCXI-1141/1142/1143. Signal names printed in

SCXI-1305 Installation Guide
Due to space limitations, a jumper, W1, inside the terminal block is used to
select the clock that goes to the SMB connector. Figure 2 shows the
location of jumper W1. Refer to the SCXI-1140 User Manual or
SCXI-1141/1142/1143 User Manual for the use of these clocks.
To connect the signal to the terminal block, perform the following steps,
while referring to Figures 1 and 2:
1.
Unscrew the top cover screws and remove the top cover.
2.
Configure each of the AC/DC coupling and ground-referencing
switches, depending on the signal you are measuring and the SCXI
module you are using. The top set of switches (S1, S2, and S3)
corresponds to input channel 0, the next set down (S4, S5, and S6)
corresponds to input channel 1, and so on. The bottom set of switches
(S22, S23, and S24) corresponds to input channel 7.
3.
If using the SCXI-1305 with an SCXI-1140 or SCXI-1141/1142/1143,
configure the SMB connector function (jumper W1).
4.
Reinstall the top cover and tighten the top cover screws.
5.
Connect the signal wires to the BNC and SMB connectors. When
connecting the signals to the SCXI-1305, follow the labeling on the
SCXI-1305 for the appropriate module.
6.
Attach the SCXI-1305 to the SCXI module using the thumbscrews.
7.
Refer to the SCXI Quick Start Guide to power on the SCXI chassis and
configure the system in software.
