Information

Accurate rise time measurements are key
Many logic families have faster rise times (edge speeds) than their clock
rates suggest. A processor with a 20 MHz clock may well have signals with
rise times similar to those of an 800 MHz processor. Rise times are critical
for studying square waves and pulses. Square waves are standard for
testing amplifier distortion and timing signals for TVs and computers.
Pulses may represent glitches or information bits – too slow a rise time for
the circuit being tested could shift the pulse in time and give a wrong value.
