The maximum DC Offset allowed on the signal generator depends on the output waveform being generated.

For square waveforms, the maximum offset that is allowed is 50% of the amplitude setting (50% of V pk-pk). The maximum offset is shown in the following figure.

If a sine, triangle, ramp, or user-defined waveform is generated, then any offset is allowed as long as the waveform stays within the +10 and -10 V amplitude limit of the board into high Z (+5 V and -5 V limit into 50 Ω load). A 2 Vpk-pk sine waveform is shown in the following figure with its maximum allowed offset setting.

Note   Using DC offset causes a reduction in DAC resolution and affects the Sync Out signal duty cycle for all waveforms except square waves. Refer to the device specifications for more information.
