How to connect ADC 11 to 2 source of waveform?

Postby cbd1095 » Thu Dec 23, 2004 1:35 pm

Hi everyone! I'm new here. I'm using PICO ADC 11 in my lab to complete my investigation on signal filtering. I wish to know how could connect the outputs from 2 signal generators to the ADC 11. The objective is to view 2 identical signal with types on filter.

If anyone could give me a brief schematic of the connection, your help is very much appreciated.

Thanks in advance

Hi

Thank you for your post.

If the signal generator outputs are BNC connectors then you could easily connect by having a BNC to crocodie clip lead and then from this connect the red to the channel input and the black to ground.

What you need to keep in mind is that the input voltage range of the ADC-11 is 0 to 5V and so the output of the signal generator must be within this range.

Hope this helps

Best Regards
Sarah

Hi

Thank you for your post.

Yes you are right it is 0 to 2.5V, my apologies.

Best Regards
Sarah
