Step response time

The step response time is the time interval required to execute a jump over a specified distance.

Detailed description

For an abrupt change to a new set position, the scanners need a certain time until the actual position matches the set position. Here, time is also required for waiting until the mirrors have settled and remain within a specified precision level.

SCANLAB specifies step response times at 1% of full scale and 10% of full scale for a precision level of 1/1000 of full scale. Specialized systems might require more revealing step response time specifications.

Hard jumps are not recommended for vector tunings; instead, a defined speed and a jump delay should be used.
