Feed my DUT with scaled signal

[toupsonx]

Hi everybody 

i want to feed my DUT with a sweep signal scaled by a H(f) a transfert function that i have already calculate feeding my dut with a white noise and get the FRF of output and input so i have H as 1D array.

You have not given sufficient information. You should also avoid acronyms (e.g. DUT and FRF can have many meanings and we need to guess :D.)

• What hardware is sending this?
• Is this RF or something else?
• What's type of device is the DUT?
• Is this plain LabVIEW or e.g. the Comm suite?

you are wright, i want to characterize a shaker and i'm working with compact rio. so first i thinked to generate a white noise and feed shaker and calculate the frequency response of out/in, then to make a test such modal analysis with sweep signal for example i wanted to know a way to use that H(f)?
