P.S. The difference between this and the NI data logger is basically:
a. the scope takes many more samples per second, and
b. the NI unit has 12 bits (4096 parts) sampling resolution, while the scope gives only 8 bits (256 parts), which is considerably less, and
c. the NI unit costs lots more, but
d. the NI logger will sample a lot more data over a longer period of time, and
e. give you many more channels for input, analog and digital.
To my mind, as a college student, the scope will do more for you, here and now.
As an aside, the scope gives you display software. You can probably get something from NI which graphs the results of the loggers data, but will cost you something more. If you know your way around MS Excel you can use its graphs function(s) to dispaly the NI results, too.
'Luck!
