An oscilloscope is usually the most sensitive, and arguably most versatile, tool on a hacker’s workbench, often taking ...

Pass/fail testing is an analysis function of an oscilloscope that shows whether waveforms meet a set of defined criteria. The criteria are defined by a series of one or more qualifying conditions that ...

Repairing radios was easier when radios were simple. There were typically two strategies. You could use a signal tracer (an amplifier) to listen at the volume control. If you heard something, the ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.

You sit down at your lab bench to debug some funny behavior in a 10-MHz clock. You fire up your oscilloscope, get your probing in place, and hit the almighty Auto Scale button, after which you’re ...

You stare at the log output. It seems okay, and yet the bug is still hiding. Was Task A missing its deadline? You don’t know. Was a priority inversion quietly breaking the scheduler? Again, you don’t ...

The first oscilloscope I ever used professionally was an old synchronized sweep instrument. Obtaining a stable display on that old oscilloscope was an art. Now I appreciate all the triggering tools ...

EE-Evaluation Engineering began in March 1962 as a vehicle for reliability topics, primarily as they related to passive components. IC failure analysis was featured in a 1968 article, and that year ...
