JT 2127 STM

The JT 2127 STM (Socket Test Modules) family has been designed for manufacturing test of PCB DIMM sockets. They offer easy insertion in standard DIMM sockets on a target board and will test all active signals as well as the analog voltages on the individual power pins (such as Vdd, Vddq, Vref and Vddspd). JT 2127 STMs thereby provide a complete structural test of the DIMM sockets.

See the tabs below for available modules and their specifications.

  • Tests connections to DIMM & SODIMM sockets
  • Measures DIMM socket power rails
  • Works using DIOS technology
