Making a Steamy, Hairy Golf Ball

By Istvan Novak

At a conference in the early 90s I heard this prediction in a keynote speech: “In 10 to 20 years, computers will look like hairy steamy golf balls.” The argument was that the many different IO cables—remember parallel printer cables?—will make computers look hairy, and because they will be much smaller, probably the size of a golf ball, they will dissipate more power and will be steaming hot. Almost 30 years later, it is time to ask: Are we there yet?

Measuring a Scope Probe Requires Two Oscilloscope Channels and a Very Flat Signal Source

By Steve Sandler

Obtaining accurate measurement data requires either accurate knowledge and accounting for the probe and fixture influence OR calibration methodology to remove these effects prior to measurement.

Power Supply Rejection Ratio Measurement (PSRR)

Sponsored By Rohde & Schwarz

Power supply design engineers often face the challenge of measuring the power supply rejection ratio or power supply ripple rejection (PSRR) of their design. The PSRR is an important parameter to indicate the power supply’s output stability. It provides information about the influence of input voltage variations on the stability of the output voltage.

Measuring and Interpreting Impedance Data

Power integrity engineers have been learning to make VRM impedance measurements to compare to the design goal or “target impedance”. Once the measurement has been performed, it’s important to be able to interpret the data. Is the result good or bad? What do I need to do to improve it? How does the impedance measurement relate to step load response and control loop stability? This webinar addresses all of these topics, providing you with the ability to perform accurate measurements, analyze the results and relate the impedance to step load response and control loop stability.
