You can use the DEQ2496 or any parametric equalizer with REW. The only thing is that REW doesn’t have a preset mode for the DEQ in the EQ filter panel (accessed under the “Equaliser” label, top left of screen), so you have to use the “Generic” mode. They only problem may be if the DEQ uses something besides “Q” as its designation for bandwidth (likely, seems to be a common situation with Behringer digital equalizers).
