simulated DAQ AI signal

[Jamieg]

Dear NI Forum,
I've written a labview VI which takes an AI from my DAQ and analyses it.
There is an option when choosing the physical channel of the DAQ AI to select a simulated DAQ ai channel, however the ai signal of this simulated DAQ channel is a sine wave.  Is it possible to alter this to a customised expected input signal?  Eg one or more sine waves with specific frequencies and amplitudes buried in white gaussian noise?
Thanks for your consideration,
Jamie

Hello Jamie,

configuration of the DAQmx simulated signal is currently not available. The signal is always a sine wave with 3% of noise with respect to the full signal. Only the timing features are accepted and the simulated modules produce the same errors as the physically available DAQ devices.

I would simply recommend to develop your application as modular as possible, i.e. one could develop two modules in LV which can be use interchangeably, one generating signals from a set of parameters (waveform type, frequency, amplitude, phase + any kind of noise) and another which performs the actual data acquisition.

Future releases will probably have this feature as few customers requested this feature.
