2 Channel USB Oscilloscope

At last! A genuinely affordable computer connect oscilloscope. USB
connect oscilloscopes out of Europe and North America have so far been
out of the price range for hobbyists, schools, and even many
professional people. Fortunately, we have been able to work with a
EUROPEAN manufacturer to produce this compact unit which is packed
with features and the European quality we've come to know.

Using the Plug 'n Play USB technology and providing full optical
isolation from the computer, this oscilloscope is easy to setup and
use, as well as providing protection for the computer. The software
(again developed in Europe) is a fully featured chart recorder,
function generator, logic generator, logic analyser, and spectrum
analyser all in one easy to use package.

We think you'll be suitably impressed by this product's price and
feature list.

Specifications
Oscilloscope, spectrum analyzer
Sample rate: 100 Hz - 200 kHz
Input voltage -20 - +20 V
ADC capacity: 10 bits
Window functions: Hamming, Hanning, Blackman, Blackman-Harris

Recorder:
Sample rate: 0.01 Hz - 200 KHz
Maximum record time: 24 hours
Input voltage -20 - +20 V
ADC capacity: 10 bit

Logic analyzer:

Maximum input/output current: 10 mA

Minimum system requirements:
Windows 2000 or XP
Pentium 600MHz, 256MB RAM.

That is basically a data logger and not an oscilloscope. The 200KHz
sample rate makes it only good for audio use up to 20KHz (giving you
10 samples per cycle at that frequency, a rule of thumb). Seems like
it only has a single input range as well, that is also very poor.

It's just a toy, don't waste your money.
