Can a digital scope do Lissajous figures?
<’REPLY You might have me there, although with the built in measurement
capabilities, Lissajous figures are no longer needed. I haven't used
them in more than 50 years. I vaguely remember them from my first
semester electronics class. :-)

### Lissajous figures might look cool, and were typ used on 50s Sci-Fi
movies,
including the original star trek series from the 60s. Makes for a great
back drop,
like it actually had a function in life.
## having said all that, I used a 4 channel Tek analog scope all the time
at work,
during my tenure at the telco. We used it for all sorts of stuff,
including calibrating mag tape units
at the time, where the timing was extremely critical. And timing
applications on digital offices, digital spans,
and precision clock ovens.
Each office had a 2 channel tek scope, plus a logic analyzer. Along the
way, I evaluated 3 different types
of Fluke scope meters. We ended up buying 12 of the deluxe versions.
After comparing the 4 channel
analog Tek vs the expensive Fluke scope meter, I opted to use the 4 channel
Tek, even though it was heavier..having
to put into my work van, and take to multiple sites. Way too easy to be
off on a tangent with the Fluke scope meters,
which are good devices, but easy to have timing readings outa whack.
They eventually worked for
my application, but that was only after extensive comparison between the
known good tek...and tweaking the
fluke scope meter to display the same info. But I never did trust em.
Then they would do stupid stuff, like the
entire menu etc.. in either spanish..or french. Meanwhile Im trying to
figure out how to get back to english.
which was not blatantly obvious.
