The UltraFLEXplus platform is the newest member of the UltraFLEX family, designed to support the next generation of digital devices. The expanded capabilities of the new system has prompted many to switch to the UltraFLEXplus, or use a combination of UltraFLEX and UltraFLEXplus to test their devices. The two platforms share many similarities, including the IGXL code environment. However, through firsthand experience upgrading and debugging test programs, we have found there are several key differences that program developers should be aware of when switching to the Plus. Through this presentation, we will share tips, tricks and lessons learned for transitioning programs between the two platforms, as well as additional considerations needed to take advantage of all improvements achieved by the UltraFLEXplus. This hands-on guide focuses on practical advice for anyone either starting on or moving to the new platform, and includes discussion of the latest instruments and innovative test techniques available.
