The Tektronix 91P32 is a 32-channel pattern expansion module for the DAS9100 logic analyzer.
Patterns can be generated with clock rates up to 25 MHz. Up to two 91P32 expansion modules can be installed in the DAS9100 mainframe to augment the 16 pattern channels provided by the 91P16 pattern generator. The 91P32 modules cannot operate without a master 91P16.
This expansion board is fully documented in the DAS9100 Operator's and Service manuals.
