Chapter 5. Product Structure 5 - 13
• The main function of the Analog Controlboard is to control the motor of 3D Probe, to
supply clocks to the entire system and to monitor the status of power.
• Motor Partcontrols the stepping motor inside the 3D Probe.
• HV Filter is a high voltage filter used in BF.
• Clock Partgenerates system Clock 61.6Mhz used in BF and BE.
• Pulser Sensing Partmonitors the status of High Voltage and current used in the BF
board.
• ATGC Partsupports analog time gain control curve used in BF.
• AC Powergenerates power for the AC & PSA board.
• Probe Part checks Probe port selection,
• Probe ID read, and Probe Insert of the PSA board at all times.

▐ Operational Principles
The operational principle of the 3D Probe is the implementation of 3D mode through the
actuation of Stepping Motor. The Motor Board performs feedback control with SIN and COS
waveforms that have a 90
o
-phase difference with the 3D Probe. Here, the 3D Probe provides a
Null Position signal to the Motor Board, and the Motor Board provides One Frame signal, which
is the standard signal for obtaining 3D images, to BE Board.
It monitors the voltage of HV Power in the BF Board and sends it to PC.
It provides the ATGC Curve to the BF Board.
