Which accessories can I use to connect signals to the front of the
SCXI-1141/1142/1143 module?
For information regarding available accessories, refer to Chapter1, About
the SCXI-1141/1142/1143.
How do I control the gain using LabVIEW?
The gain of each SCXI-1141/1142/1143 channel is automatically set based
on the channel limits used in setting up the acquisition. You usually use the
LabVIEW DAQmx Create Channel VI to set the channel limits. If the
channel limits are not explicitly set, the SCXI-1141/1142/1143 defaults to
the gain setting entered when the module was configured using MAX. For
more information, refer to Chapter 3, Configuring and Testing.
How do I perform external triggering using the SCXI-1141/1142/1143?
For analog triggering, use the data acquisition device analog triggering
functionality through pin PFI 0. Verify that the E/M Series DAQ device
supports analog triggering. For more information about analog triggering
with the SCXI-1141/1142/1143, refer to ni.com/info and use the info
code rdahtu.
For digital triggering, use the data acquisition device digital triggering
functionality through pin PFI 0. All E/M Series DAQ devices support
digital triggering. For more information about digital triggering with the
SCXI-1141/1142/1143, refer to the DAQ device help file.
