4461 output issue

[gaylordelatour]

Hi everyone,

I have a problem with one of my output, the output generation is incorrect,  it seems to be a hardware problem.

The card working properly until now, and i haven't change the connection before the onset of the problem. The output is connect to a voltage amplifier and to one input of the card.

Now when I tired to generate with max a 10V sinus, i have this (joint file)

Any idea of where it may come?

Thnaks you

Hello gaylordelatour,

Nice details screens ! Can you try the same measurments with your voltage amplifier disconnected from 4461 ? To try to identify where the issue comes from.

Thanks in advance for your feedback.

Best regards,

In fact I took these screen with only the output AO0 connected to the input AI0, the two other (A01 and AO1) are not connected, the scheme was the connection configuration when I discovered the problem.

So it's very weird nothing is supposed to damaged the output in this configuration, the voltage amplifier work fine I use it with the second output of the card now.

You card may be damaged, you can ask for a repair I think,

Did you check the negative power supply voltage and grounding of the amplifier?
