Picoscope 2202 versus ADC 200/20

Postby Matt Tindale » Thu Jul 14, 2005 5:02 pm

I note that the 2202 has an almost identical spec to the ADC 200/20. Except for the 2Mhz bandwifth on the 2202, compared to 10MHz on the 200/20.
Forgive my lack of understanding but what aspect of measurement will this limit? I thought perhaps resolution but the resolution is the same for both models.
What sort of V accuracy does 8 bits get you?

I am buying for a school Physics department for use in A-level (16-18) Physics courses.

Many thanks.

Hi

Thank you for your post.

The 2MHz bandwidth with affect the speed of signals you can put into the unit, therefore you cannot really put a signal greater than 2MHz in frequency into the unit as it will not be able to display this correctly.

The accuracy of both units is 3% and the 8 bit resolution gives you 256 points on the vertical scale. Obviously as the unit has different voltage ranges this utilises the resolution to the full.

Hope this helps

Best Regards
Sarah
