I was just wondering if LabVIEW SignalExpress 2010 had an overload indication/rejection feature to tell me if any channels on my PXI card are overloaded, and if so where I could find it. I am currently using a PXI-4462 card with the trial version of SignalExpress.
Thanks

Sdltd,
I am assuming by overload on a channel you mean if a channel's voltage has gone above the max input (42.4 V Peak to Peak differential) on the PXI-4462 device. There is no indicator given by hardware which tells the computer in any fashion that there has been an input that exceeds the max voltage. The only way that you would be able to tell if it went over the max voltage would be if the device rails at the peak voltage. I would not recommend testing the limits of your devices as this as this could cause damage to your device. What you could do in SingalExpress would be to set an alarm so that if the channel goes above a certain voltage, lets say 40 V pk to pk differential, the DAQmx acquire would stop. LabVIEW SignalExpress 2010 has capabilities for alarms, while the SignalExpress LE does not.
