In an open loop, a point-to-point controlled CNC drilling machine, a stepper motor, producing 200 angular steps per revolution, drives the table of a drilling machine by one angular step per pulse generated by a pulse generator (shown in the figure). Each angular step moves the table by one Basic Length Unit (BLU) along X-axis with a lead screw having a pitch of 4 mm. If the frequency of the pulse generator is doubled, the BLU will______
