SPSS does not have a procedure to perform Rasch analysis. Winsteps and
Bilog are among the specialty packages that can perform a Rasch analysis
directly. In a general sense, a Rasch analysis could be performed using
any tool that can handle multi-level data with dichotomous outcomes and
random effects, for example HGLM in the HLM package. But this excludes
SPSS.
Good luck.
