PCIe 6351 output voltage limited

My card is connected to an NI BNC-2110 and I am trying to output a Sinus-wave with an amplitude of 10V  from one of its analogue outputs and display it directly onto an oscilloscope. The signal does follow in the range of -0,5V up to 0,5V, however, the voltage does not surpass 0,5V nor drop below -0,5V. I tried to instruct the signal via NIMAX as an adequate task as well as via python (code attached below).

Thank you very much in advance for your help!

Do you have attenuation on the connection from BNC-2110 to the oscilloscope?

Can you try to do a loop by connecting AO to AI on 6351?
