NI 7833R accuracy

I need some help in interpreting the data sheet for the NI 7833R FPGA module. On page 3, the analog output "absolute accuracy at full scale" is said to be 5.88mV. When I measure the zero value output on one of my output channels with an oscilloscope, I find a noise level of about 10-12 mV. Is this according to specification? I.e does the 10-12 mV noise correspond to a 2 * 5.88mV peak-to-peak in absolute accuracy, or am I picking up additional noise in my measurements ?
