BP-DAC11001EVM: Is it normal for the DAC output voltage to fluctuate by 30uV?

Part Number: BP-DAC11001EVM


I tested with BP-DAC11001EVM, the current situation is that the hardware connection is OK,

I don't know how to modify the output value of the dac, the current test dac output value is fixed -5V.

I can't modify the output value of the dac, after I do, its parameters will immediately return to their default values.

In addition, the dac output, connected to the 3458a multimeter to measure the voltage fluctuation is about 30uV or so.
The configuration is as follows:

What I want to know is, when you guys test the value of the dac output with the demo, under normal circumstances, how much amplitude is the fluctuation of it when you test the value with the 3458a? How many uV?
