5-11-4 TX Power Supply
5-11-4-1 General Description
The TX Power is a switch mode power supply module. It is used to generate two symmetrical pairs of
digitally programmable voltages for the transmitters in the Vivid 7 scanner.
A fixed Probe MUX voltage with either +/- 95 VDC or +/- 100 VDC, depending on TX Power Supply
model, is used by the multiplexers in Linear Array and Convex probes with more than 128 transducer
elements.
• It is enclosed in a metal frame that slides into the Card Cage.
• The module connects to the Motherboard (Backplane) through a 32 pin connector
• One or two guide pins, located between the two upper mounting screws, fits into corresponding
hole(s) in the Card Cage. This “key” is used to prevent it from being plugged into scanners that use
similar, but not compatible power supplies.
- The TX Power with one guide pin is used in Vivid 7 produced with software version v3.x and
earlier, and without 4D.
- The TX Power with two guide pins was introduced for use in Vivid 7 with software version v4.0,
and is needed for all Vivid 7 with 4D.
