5-8-3 Transmitter Board (GTX)
5-8-3-1 General description
Two Transmitter Board models have been used in VIVID E9:
• GTX-TLP 3.0 with 64 channels per card
• GTX-TLP192 with 192 channels per card (Introduced August 2011)
GTX-TLP 3.0
The GTX-TLP 3.0 contains 64 individually controlled transmit channels. In VIVID E9, either three or four
boards are used, giving a total of 192 or 256 TX channels.
• The 3V-D probe, used on BT’08 systems, requires 256 TX channels, so four TX boards with 64 TX
channels each, are used. Each channel from the TX boards is connected to 4 elements in the probe,
so we can transmit on 1024 elements (256 x 4).
• All other probes use 192 or less TX channels. In this case, three TX boards with 64 channels are
used.
GTX-TLP192
The GTX-TLP192 contains 192 individually controlled transmit channels on one board, and replaces the
three TX boards with 64 TX channels each, described above.
The GTX board(s) provide transmit pulses via the Front Plane (XD BUS) to the Relay board and then
to the transducer array (the probes).
NOTE: The GTX-TLP 3.0 and the GTX-TLP192 requires different Front Plane cards.
