Modules with product numbers ending in "B" are compatible with 54600B-series scopes and the 54645A/D. Modules ending in "A" are compatible with all 54600 products. 54645A/D and the 54615B and 54616B/C use the 54655A and the 54656A for I/O only. Note that the 54620A/C logic analyzer can use any of these modules, but it uses the modules for I/0 only.
