Test equipment for actuator frequency response

I am looking for a data acquisition system to replace an old Spectral Dynamics Siglab 42-20 system that I use to collect the frequency response of a smart material actuator our company manufactures. We currently run a stepped sine test between 50Hz and 2000Hz. This tests dwells at 50Hz, collects 5-10 response samples through a narrowband filter, then steps to 60Hz. The process repeats over and over until reaching 2000Hz.

I am having difficulty finding a new system to run this test. Most software seems to be written for swept sines, not stepped sines. Does anyone know of a good test suite that is capable of running stepped sine tests? Also, would a tracking filter on a swept sine work similarly to my stepped sine test? Thanks for your help!

Scott
