5-3-10-8 Test points on the TX128 board
 
NOTE: The Voltages on these test points are approxi mately one tenth (1/10) of the TX Voltages used 
by the transmitter circuits. (The exact [calcu lated] value is 10/101). The measured values 
depends on selected scanning mode  and the Acoustic Power adjustment.

5-3-11 Transmitter Board, TX12 8 (version used before BT’05)
5-3-11-1 General Description
The Transmitter board (TX128) contains 128 individually controlled transmit channels and provides 
transmit pulses via the XDBUS board to the Relay boa rd and then to the transducer array (the probes).
Frequency-, delay- and pulswidth parameters for the TX128 board are received on the FE_BUS...
