Set Enhanced Alias Rejection

[joefootdale]

I'm using Signal Express and would like to acquire data at a sub 1kHz rate. Doing that I get error code -201001, suggesting that I need to set the Enhance Alias Rejection Enable to value True for the 4472 boards I'm using. Searching this problem I found how to do that in LabView, but nothing for signal express. I have a separate metrology system that I'm trying to synch the Signal Express data with that is limited to sample at 100 Hz. What is the best way to collect data at a sub 1kHz rate? Thanks for any help.

Hi Joe,

Unfortunately it is not possible to sample at a rate of less than 1K using the 4472/SignalExpress.  My recommendation would be to decimate the data to effectively reduce the sampling rate to 100 Hz.
