The Tektronix HFS9003 Programmable Stimulus System is a VXIbus-compliant, modular mainframe designed to generate high-speed electrical stimulus signals for semiconductor device characterization. The C-size mainframe accommodates a CPU card, time base card, and up to three pulse or data generator cards, delivering up to 12 channels of stimulus with optional configurations supporting 640+ phase-locked channels. Built on fully digital architecture, the system characterizes CMOS, ECL, ACL, BiCMOS, and GaAs devices with 1 ps timing resolution and independent edge placement on every pin.
