30 Intel® Xeon® Processor 3500 Series Datasheet Volume 1

2.11.3 Die Voltage Validation

Core voltage (V

) overshoot events at the processor must meet the specifications in

Table 2-16 when measured across the VCC_SENSE and VSS_SENSE lands. Overshoot

events that are < 10 ns in duration may be ignored. These measurements of processor

die level overshoot should be taken with a 100 MHz bandwidth limited oscilloscope.
