Fig 4-3 Schematic diagram of the probe board
The probe board offers the connection to the probe, and connects the channel of probe's port to the
channel of receiving/transmitting module in main unit. The probe board is subordinate to the engine
board, and manages the probe with the engine board. The functions of probe management:
The notice for probe’s change when it is in the place.
Each in-place signal of the probe is connected to CPLD. CPLD informs DSP_FPGA via an
interruption as each time the change occurs.
General control of the probe - power supply management
CPLD manages the power-up and power-down of each probe’s socket.
Supply the power to flash when accessing to ID as the probe is connected. Enable the probe in
which the channel needs to be switched. The switch circuit inside the probe also needs the
power supply.
After the probe is unplugged, shut down the power supply to the probe and notify the engine
board of stopping transmitting.
General control of the probe -probe recognition
CPLD obtains ID code as SPI accesses to each Flash inside the probe and informs
DSP_FPGA via SPI.
The interconnection to socket's signal
The receiving and transmitting POUT signal of regular probe can be switched among many
probes on the realization of CPLD controlling the relay.
The switch of control signal on the probe containing high-voltage switch is produced by
DSP_FPGA. The probe distributes out to each probe’s socket.
After being selected and distributed, the control and signal’s feedback of various special probes
(such as 4D, bi-planar, TEE) are connected to the engine board. The selection and the distribution
is realized by CPLD which is controlled DSP_FPGA.

DC from the aspect of power supply transfer flow.
DC includes DC-DC module, PHV module and battery assembly.
AC includes AC-DC module, assistant output module and AC interface module.
Closely related to ultrasound services, the voltage circuits in DC part are quite large, in which the
performance also occupies high-performance. The coupling of DC part keeps tight as well. At the
same time, the space arrangement also keeps close to ultrasound service. However, AC, to some
extent, couples little with ultrasound service. The volume is comparatively larger, which may lead
away from ultrasound service.
DC and ultrasound services are located inside the main unit box above the base. Whereas, AC is
located inside the power supply box below the base. Two parts are connected by cables. The output
path for heavy current should take pressure drop, the security, fool-proofing and the reliability into
consideration.

4.5.2 DC-DC Module
DC-DC module provides public power supply (for example, 12 V, 3.3 V) or specialized power supply
(for example A±5.7 V) to ultrasound service module. It meets the requirements of the voltage and
the current. The service module is able to fulfill the switching of the power supply.
4.5.3 PHV Module
PHV is the acronym of Programmable Height Voltage. The transmission voltage used in the
transmission circuit needs to be adjusted based on varied probes, modes and the depth. Hence, it
requests the program control for the transmission voltage.
PHV module on DC-DC board refers to PHV board.
Absolute value of output voltage is 1.5±5%V~80±5%V; 100 V.
4.5.4 Time Sequence of Power-On
The time sequence of main unit's power-on:
1. Connects AC power supply to main unit.AC-DC outputs the standby power supply 5VSTB by
default to supply the power to EC on PC board. The in-place AC indicator on the control panel
remains on.
2. The user presses the power-on button on the control panel. It triggers PWRBTN_N to supply
EC.
3. EC interacts with PC module according to ATX time sequence. After the standby status of PC
module rises higher, EC notifies AC-DC module of enabling 12_ACDC of non-standby power
supply and outputs to DC-DC module to complete the transfer. Transfers varied power supply,
including PC12 V. After PC12V stays stable, EC module notifies of enabling PC module. Then,
PC module starts BIOS. The power-on indicator on the control panel blinks during the process.
If the indicator blinks in orange, it indicates SUS_S3_N of PC module does not rise higher. PC
module is poorly assembled or corrupted. If the indicator blinks in green, it indicates PC12V is
not powered on. The failure may occur to power supply module. The indicator remains green if
it works well.
