Chapter 13 PI-MAX4: 1024i-RF and RF Modulation 193
Example
The following Phase Sweep values have been configured:
• Range Start: -720°
• Range End: +360°
• Increment: 90°
The total sweep length is 1080° in 90° increments/steps which corresponds to 13
data points. Since Range Start < Range End, the sweep proceeds in a positive/
counterclockwise direction.
LightField “shifts” the programmed sweep starting point so that it starts at 0°.
Table 13-1 shows the corresponding/calculated values for each step in the sweep.
