Scan Types
Three types of scans may be activated: smooth scan, stepped scan, and random scan.
A smooth scan slowly pans between the left and right scan limits, starting at the left scan limit.
When the right scan limit is reached, the scan reverses. Figure 55 illustrates the smooth scan.
A stepped scan pans slowly, pausing briefly every 10° between the left and right scan limits.
Once the right scan limit is reached, the scan reverses. Figure 56 illustrates the stepped scan.
Each arrowhead represents a 10° step in the scan.
