# Steps Per Line

Defines the number of encoder steps for each image line. A step is a complete cycle of the encoder signal or signals, depending on the encoder you use.

For a single-line hardware encoder, a complete cycle is equivalent to two signal transitions.

For a quadrature hardware encoder, a complete cycle is equivalent to four signal transitions.

The following image shows how steps per line correlate to signal transition for different encoders:

The available values are 0.25–4000000.

Note: Increment by 0.5 for single-line hardware encoders, and by 0.25 for quadrature hardware encoders.
Note: The Steps Per Line parameter is only available when the Line Trigger Type is set to Hardware Encoder.
