Introduction

DAC Format Modes

NRZ: DAC A sends value for

whole sample period

Each channel internally uses two DACs (A & B). Each DAC usually

contributes to the signal 50% of a sample period.

The following three DAC format modes are available:

•

NRZ (Non Return to Zero)

•

DNRZ, (Double NRZ)

•

Doublet

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).

DNRZ: DAC A and B send same value

Figure 1

Doublet: DAC A sends +Value,

DAC-B sends –Value
