RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

These tech-centric jokes,
song parodies, anecdotes and assorted humor have been collected from friends and
websites across the Internet. This humor is light-hearted and sometimes slightly
offensive to the easily-offended, so you are forewarned. It is all workplace-safe.
in the early days of creating "art" with waveforms, the best that could be done was making some spiffy Lissajous patterns
on an oscilloscope by driving the x- and y- axes with various inputs. Lissajous curves are the ones that look like
they were made with a child's
Spirograph. Really high-end waveform artists figured out how to drive the z-axis (intensity) to blank out the
pattern in the right places to draw more sophisticated pictures. As is usually the case, with the passage of time
comes an evolution to higher-order applications, like orchestrated Lissajous
Sometime, however, artwork appears quite by accident and takes a sharp-eyed observer to recognize
the image for what it is. Think of all the images of Mary that have been found everywhere from a
stained subway wall
to a grilled cheese sandwich.

visitor Tony T. has had just such a revelation while viewing a multi-carrier waveform for WCDMA on an Agilent spectrum
analyzer. He has titled it, "One Finger Salute." Maybe that waveform was trying to tell him something...
