Swept Sine Phase Response Issue

[CantThinkofaname]

Hello,

I'm swept sine VI from sound and vibration which looks like this.

I am just trying out simple frequency response where I simply wire output signal to two input terminals (stimulus and response chanels) - so I should get frequency response magnitude equal to "1" at all frequencies and phase equal to "0" at all frequencies. However there is a phase shift which rises linearly with frequency. It says that I can customize the interchannel delay in DAQmx by setting the AI Convert Clock Rate. I'm kinda confused as to how to do it. Can anyone help me?

Thanks!

Stephen
