Digital quadrature outputs. Signals are RS-422 compatible square waves. Pulses are 90° out
of phase with B+/B- outputs.
Digital quadrature outputs. Signals are RS-422 compatible square waves. Pulses are 90° out
of phase with B+/B- outputs.
The Index Window defines one particular fringe on the grating surface. The Index Window
signal is a TTL compatible pulse, and is approximately 40 um wide. Note that this signal is not
synchronized to the A or B signals.
