Auxiliary modules

There are two types of DIMMs, general-purpose Digital Input/Output Scan (DIOS) modules and Socket Test Modules (STM).  DIOS modules plug into standard 168-pin DIMM sockets and operate over a range of voltages and TCK rates, up to 45 MHz.  Programmable functionality is a feature of some of the DIOS modules, enabling them to be used to enhance functional testing.

Typical application of the STMs is to test connector sockets within the target system.  STMs are offered with pinouts from 100 to 300 pins, including several small-outline pinouts.
