The Elusive Glitch - Part 2
Hi All,
This month, I describe in my Technical Tidbit article (www.dsmith.org) a
way to accurately pinpoint the source of a waveform glitch. It takes
last month's article one step further than just determining if a glitch
is likely coming from an external source instead of the circuit being
measured.
The technique uses an extra channel(s) of a scope to determine if the
glitch is real or a result of external EMI and is reminiscent of the
amateur radio transmitter hunts I participated in as a teenager (except
in the time domain this time). Knowing this information can save a lot
of engineering time in the lab and has become more important as circuits
and measurement instruments have increased in speed. Equipment can now
be affected by EMI sources that have not been a problem until the last
few years.
