Fundamentals of Signal Integrity |
 By definition, integrity means "complete and unimpaired."
Likewise, a digital signal with good integrity has clean, fast
transitions; stable and valid logic levels; accurate placement
in time and it would be free of any transients.
Evolving technology makes it increasingly difficult for system developers to produce and maintain complete, unimpaired signals in digital systems.
The purpose of this primer is to provide some insight into
signal integrity-related problems in digital systems, and to
describe their causes, characteristics, effects, and
solutions.

| AMETEK Extends Industry Leading Sorensen SG Series of High-Power DC Supplies |
The Sorensen SG Series of programmable power supplies has been expanded to include output voltages from 0-1Vdc to 0-800Vdc. This expansion of capability nicely meets the increasing voltages required for hybrid vehicle and inverter test markets and low voltage high current applications such as battery charging test stands.
The SG is available with 5kW, 10kW or 15kW in a 3u chassis, allowing up to 5 chassis to be paralleled for maximum system power of 75kW. Paralleled units operate like a single supply. The SG Series is designed for exceptional load transient response, low noise and the highest power density in the industry. Its industry-leading power density is enhanced by a stylish front air intake that allows supplies to be stacked without any required clearance between units.

Model 2651A tests high-power devices such as high-brightness LEDs and power MOSFETs
Keithley Instruments has introduced its fourth-generation SMU (source-measure unit), the Model 2651A SourceMeter. Designed for testing high-brightness LEDs, power MOSFETs, and other power devices, the 2651A can produce 200 W continuous power or 2000 W pulsed power. Continuous power ranges from ±40 V at ±5 A to ±10V at ±20 A. In pulsed mode, the 2651A can produce at ±50-A current pulse at up to ±40 V. If you need more power, you can operate two SMUs in series for up to 80 V or in parallel for 100 A.
The 2651A can produce stimulus pulses with as short at 100 μs. Programmable pulse-timing resolution is 1 μs. The programmable duty cycle ranges from 1% to 100%, which is DC.
