10x attenuator for PCI-6071E

[Larry_Kubier]

I need to design a 10x attenuator circuit for my PCI-6071E.
I am designing a 24 channel load card that will require a 10x attenuation circuit. The SCC-A10 is a solution, but I would have to route the signals off the load card and then back on.

Hey Larry,

If you are just looking for a circuit for attenuating a signal by 10, then I would suggest an non-inverting amplifier circuit. Op-amps are very inexpensive, and you can create an attenuating circuit with an op-amp and some resistors. I have included a link below that shows how to construct a non-inverting op-amp circuit. You'll just need to use the correct resistors to make the circuit divide by ten (gain = 0.1).

I hope this helps.
