The following three DAC format modes are available:
NRZ (Non Return to Zero)
DNRZ, (Double NRZ)
Doublet
In addition, the following format mode is also available:
RZ (Return to Zero)
It is not specified but available as over-programming.
For more details on the DAC format modes, refer to the section “Dual-Core DAC
Architectures” in the Fundamentals of Arbitrary Waveform Generation Reference
Guide (Manual Part No. M8190-91050).
