Represents a PVT buffer with this number on a device. A PVT buffer is a place to store a queue of PVT actions.

The following example illustrates how you can obtain an instance of this type:

from zaber_motion.ascii import Connection

connection = Connection.open_serial_port('COM3')
device = connection.get_device(1)
pvt = device.pvt
pvt_buffer = pvt.get_buffer(1)
