How to connect ADC 11 to 2 source of waveform?

Post by 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

Hi Sarah

I was under the impression that the volt range was 0 to 2.5 volts.........


Product ADC-11/10 ADC-11/12 ADC-22
Resolution 10 bits 12 bits 10 bits
Number of input channels 11 11 22
Input voltage range 0 - 2.5 V
Typical sampling rate(measured on 100MHz Pentium) 10kS/s (10,000 samples per second)
Linearity 1 LSB at 25C
Accuracy (of FSD) 1% of FSD 0.5% 1%
Input overvoltage protection 30V
Input impedance >1M
Digital output voltage typically 3-5 volts, depending on computer and load
Digital output impedance approx 1-3k ohms depending on type of computer
Input connector 25 way female D-type
Output connector 25 way male D-type (connects to PC printer port)

Hi

Thank you for your post.

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

Best Regards
