One of the key features of the Quantum Design PPMS is its capability to interface the automated PPMS MultiVu software with user created application programs. This application note describes how a user’s program can respond to advisories and access third party instruments. At this time, Quantum Design has created template programs using Borland’s Delphi TM , Visual Basic, and Visual C++, which will simplify the process of receiving advisories. This application note provides PPMS users with a tutorial introducing the basic concepts using Delphi to receive advisories and provides a general understanding of how system interfacing can be done on the PPMS. It should be noted that this application note IS NOT a substitute for learning Delphi nor understanding how to perform general instrument interface using GPIB. We assume that you are familiar with both subject areas and that you only need the specific information pertaining to the PPMS software. This application note only provides general guidelines in understanding the linking procedures for the PPMS.
