摘要： The present invention assesses memory (DIMM) strength by calculating frequency content of a radiated field which is collected by an apparatus, such as a dipole antenna. Radiated field is created by accelerated charge, which is a function of the slew rate or DIMM strength. Radiated power is directly proportional to the frequency at which bits are driven. By separating the radiated field from the near field or stored field, the DIMM strength content is isolated from other functional DIMM issues, such as tRCD latency, refresh cycles, addressing mode, etc. By examining the radiated power, the disadvantages of the prior art, such as by probing the DIMM's contacts, are avoided.

摘要： A method for testing a printed circuit board to determining the dielectric loss associated with the circuit board material relative to a standard. Dielectric losses in the material generate heat when a high frequency electronic signal, such as a microwave frequency signal, is communicated through a microstrip that is embedded within the printed circuit board. The temperature or spectrum at the surface of printed circuit board is measured and compared against the temperature or spectrum of the standard to determine whether the material under test is acceptable. While various temperature measurement devices may be used, the temperature is preferably measured without contacting the surface, such as using an infrared radiation probe.

摘要： A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a memory module system and DIMM connector is provided. A DIMM connector includes a plurality of DIMM sockets for receiving a corresponding plurality of DIMMs in a radially oriented, angularly spaced orientation. The DIMM sockets are connected in parallel at a memory module junction so that socket terminals of each DIMM socket are joined to the same relative terminal of all the other DIMM sockets along electronic pathways of substantially equal length. A memory controller selectively communicates with the DIMMs via the DIMM junction. By virtue of the improved topology, impedance within the DIMM connector may be better matched to minimize reflections and improve signal quality.
