Use this value for both the calibrator output and the oscilloscope offset setting.

Due to system architecture differences between MSO/DPO4000B oscilloscope models, if the bandwidth of your model is less than 1 GHz, do not use the 50 
term
ination setting on the oscilloscope to test offset accuracy. In order to tes t offset accuracy at the 50  termination setting for models less than 1 GHz, instead
usethe1M termination setting only. For 1 GHz models, test the DC offset accuracy at both the 50  termination setting and the 1 M  termination setting.
