Test station: Spectrum Hybrid Modeling, DSM and Flash Programming

Advanced applications programming allows the programmer to make full use of the This course is designed for GR228X engineer level trainees with experience of developing in-circuit test programs for the GR228X. The course covers a review of high speed modelling concepts, hybrid modelling, serial programming, DSM hardware and multiplexing issues. Flash programming is studied with hybrid models using the flash tool to generate code to program a flash device. In the serial programming we analyze the timing diagrams in the device datasheet to part them into hybrid macros. In serial programming we also study real time data to program into the device.

Intended Audience

Students who have attended the Level 1 and 2 Applications courses with at least six months of programming GenRad’s and Senior level test engineers.


Students should have a good understanding of digital electronics, be able to interpret circuit schematic diagrams, and possess GR228X programming experience.
