VXI VT1538A user manual Rotationally Positioned Pulse Output

Rotationally Positioned Pulse Output

This means that the E1538 will generate pulses which are positioned by angle (usually shaft angle). The rotational pulse function requires a rotational reference, and this is provided by the SENS:RVEL function from the SCP’s first channel. There are four related commands that set up rotational pulses. Combinations of these commands can set up four different rotational pulse modes. Figure 20 shows these modes and the command sequence for each. Following Figure 20 is the command reference for all four commands. Following that are examples of each of the four modes.
