meaning the pipeline delay for updates to frequency, amplitude, and
phase will not be equal.
See the DATA LATENCY (PIPELINE DELAY) section in the Specifi-
cations table of the AD9959 data sheet for the exact timing delays
with and without this feature enabled. Also, refer to the Single Tone
Mode-Matched Pipeline Delay section of the AD9959 data sheet.
6. DAC Full Scale Current Control
Use the DAC Full Scale Current Control section to scale the
output current of the DAC. Select either Full Scale (default setting),
½ Scale, ¼ Scale, or ⅛ Scale for the DAC output current. See
the Scalable DAC Reference Current Control Mode section of the
AD9959 data sheet.
7. Output Waveform
In the Output Waveform box, select either a Cosine(x) or a
Sine(x) function for the angle-to-amplitude conversion. The default
setting is Cosine(x).
8. Phase Accumulator Control
The Clear Phase Accumulator and Auto Clear Phase Accumula-
tor have the same basic functionality as described in the 3. All
Channel Accumulator Control section of the Chip Level Control
window. The difference is that here the function is channel-specific.
