Hardware Principle 4-3

The probe board supplies power to corresponding Flash of saving probe ID when reading
probe ID, and Flash power shuts off after getting probe ID.

Support two 156-array probes (A and B), and only one probe could be chosen by relay
switching on the probe board.

Support 192-array probe and bi-planar probe.

Support 192-array probe and bi-planar probe; the probe board controls the probe 5V output;
the main board supplies the ±95V output to 192-array probe or bi-planar probe.

Support 4D probe; recognize the probe via the ID code; switch the 4D drive signal via the
electrical relay to make the 4D probe work normally.
4.2.2 Main board
The main board could be divided into two parts: front-end of the main board and back-end of the
main board.

Figure 4-4 Principle Diagram of Front-end of the Main Board
As shown in the figure above, ultrasound front-end internal structure consists of ultrasound
receiving module
（
Rx1~Rx64
）
, ultrasound transmission module
（
Tx1~Tx64
）
, high-voltage isolation
module
（
HVISO
）
, BF FPGA module, DSP FPGA module ,PCIE_PHY module and so on.
Function describes as following:

Support 32/64-channel high-voltage isolation
（
HVISO
）
to protect ultrasound receiving
module
（
Rx
）
to avoid ultrasound transmission high-voltage contamination.
