digital oscilloscope



Raymond A. Rogoway wrote about his Digital Oscilloscope (see below).
Is it true that having an ULI I do not need "Digital Oscilloscope"? Can
all John's demos be performed with Vernier's "Sound" for Macintosh? What
is the highest sampling rate of Sound? What are real advantages of using
Digital Oscilloscope?

Digital Oscilloscope cannot be used with the ULI. It is self contained.
It can operate with the internal mic on the Mac and even has a feed-through
so that you can hear to sounds. You can adjust the triggering point or let
it free run, just as a normal oscilloscope. It also has a frequency meter
mode in which a frequency meter (counter) is displayed in large numbers
instead of the oscilloscope. What it lacks that the Vernier stuff has is
a fast fourier transform feature. The Vernier ULI uses a software package
called "Sound" in which you can have multiple screens, triggering, and a
FFT function, along with curve fitting. The software is cheap.
