In LabVIEW, can I use different input limits for the same SCXI-1125
channel if I repeat the channel in the SCXI channel string array?
No, the SCXI-1125 cannot dynamically change the gain settings during
scanning. Therefore, channels with similar input ranges should be grouped
together in the channel string array. Make sure that repeated channels in
different indices of the channel string array have the same input limits in
the corresponding input limits array.
In LabVIEW, can I use virtual channels with parallel mode channels
on the SCXI-1125?
Yes, virtual channels work with parallel mode operation on the SCXI-1125.
The E/M Series DAQ device must be directly connected to the module in
parallel mode operation. Also, virtual channels that use built-in CJC are
disabled and cannot be used in parallel mode.
In LabVIEW, can I use the calgnd channel string when the SCXI-1125
is in parallel mode?
Yes, you can autozero the SCXI-1125 in LabVIEW when using the module
in parallel mode.
