Error in NI 9263 output

[matin.khalili68@gmail.com]

Hi,

I have an NI cDAQ-9178 along with two analog input and output cards, namely NI 9239 and NI 9263. To test these two cards, I utilized MATLAB to generate a 1000 Hz sine signal with an amplitude of 10V on one of the channels of NI 9263. Subsequently, I connected this channel to one of the channels of NI 9239 to capture the signal and plot it using MATLAB. The sample frequency for both cards was set to 5000 Hz. In this scenario, the collected data exhibited a 2V error in the amplitude of the signal, despite the correct frequency as shown below. I am seeking assistance in identifying the root cause of this issue. I checked with different sample frequency the problem exists just the error is increasing and decreasing.

 Thanks
