Hardware setup - creating a function generator

[glskinner84]

My hardware:

cDAQ-9174 (4slot) with a...

NI9215 (AIO) and a

NI 9401 (DIO)

I have a accelerometer (analog) signal that I would like to perform a sweep function to get resonance( peak amplitude). I would eventually like to display this sweep( amplitude vs Frequency) so I can get a halfpower curve and take automatic frequency measurements when I want. 

My frequency range is 10hz-120hz.

My accelerometer voltage varies from 10mV-10V. 

I'm having trouble understanding the concept behind creating a function generator with the hardware I currently have. (terminal wiring, task management in labview, etc.)

I understand that my cDAQ-9174 has internal clocks that I could use to perform this sweep, but I'm at a loss on how to go about wiring the hardware. 

My mail goal is to start using Labview to perform a digital sweep. I am currently using an analog FG.

I'm a little confused about your setup.  So you're saying you already have an Analog FG but you also want to do it with the cDAQ?  If so, simply use a BNC cable from one terminal of 9215 to another on the 9215.  Then set one as input and the other as output.  This way you can generate a waveform in the output and the collect the data through the input.
