Problems with EQ tool

Hi John and all.
I'm using the EQ tool to study the topology of some filters.
I created a flat response and phase measurement at 80dB and from there I am trying to apply some filters.
I noticed that in version 5.30.2 the GENERATE MEASUREMENT FROM PREDICTED option does not have the right phase, while the GENERATE MEASUREMENT FROM FILTER option is truncating the response at 200Hz.
Am I doing something wrong?

The IR windows settings is truncating the response. Change the right IR window to a larger number. 500ms is commonly used.

I didn't know there was this link between IR window and EQ
Thanks!

Why create a dummy flat measurement? Just use the filter response.

you're right, I wasted time
