This appendix lists common questions related to the use of the SCXI-1125.
The SCXI-1125 is backward compatible with the SCXI-1120, but what
are the major differences between the SCXI-1120 and the SCXI-1125?
Table D-1 compares the major specifications and features of the two
modules. Other specifications and features of the SCXI-1125 are the same
or very similar to the SCXI-1120.
