DC Offset
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 Vpk-pk). The maximum offset is shown in the following figure.
For sine, triangle, ramp waveform or a 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 specifications for more information. |
