Figure 6-3 Principle Diagram of Z5 Series’ Probe Board
The function of Z6 series probe board describes as following:
The ultrasound signal is transferred from 64-channel to 128-array by the high-voltage
switch on the probe board.
Probe information could be obtained by probe board via reading probe online signal and
probe ID.
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 to work normally by 5v output of the probe
broad.
The main board supplies ±95v output to 192-array probe and bi-planar probe to work
normally.
