Analog Vs. Digital; Where Can I Buy A Soar - scope LSU VL-7EX II User Manual

Analog vs. Digital

The type of output refers to the types of devices that can be used to display the images created
by the scope. A digital scope has to be connected to a computer, usually via a USB cable.
Software needs to be installed on the computer before using the instrument. Analog scopes,
however, are true "plug and play" devices–you don't need to install any software to operate them.
They can be connected directly to a television, DVD player, projector, interactive white board, or
any other display that has a yellow video input.
Yellow video inputs jacks indicate devices that can display analog signals. On the left are shown typical connections
for a television (yellow is video, red and white are audio), on the right are connections for a digital projector.
Any analog scope can be connected to a computer, but this must be done with the help of a
converter. For example, the "New" Scope-On-A-Rope education kits come with a converter and
software, but there are many other options available.
Converters change analog output of SOARs to digital format for display on computer or other digital device. The
converter on the left (black) is part of the VL-7 Education Kit; on the right (white) is a commercially available model.
Considering that everything is moving towards digital technology, why would anyone want an
analog scope? There are several reasons:
No installation disc is necessary; there is no software needed.
•
You get better resolution. (This seems counterintuitive, but it's true!)
•
You have more display options—any television, projector, or active board.
•
You have more software options. (Again, this seems counterintuitive, but there are many
•
digital converter/ software packages available that make it possible for your analog scope to
work with a great variety of software.
software that comes with them.)
