4-5-1-1 Introduction
There is no need to do any special tests on the Power Supplies if there don’t seems to be a problem 
that may be related to the Power Supplies. 
4-5-1-2 Power Supply Adjustment There are no adjustments on the power supplies. The  DC Power is self-regulated. If a voltage is outside 
the specified range, it means that something is wrong,  either with the power supply itself or with a unit 
connected to that sp ecific power outlet.

Section 5-2
General Information
5-2-1 Introduction
The Vivid 7 ultrasound scanner can be used with both phased array and linear array ultrasound probes 
and Doppler (Pedof) probes.
The system can be used for:
• 2D Gray Scale and 2D Color Flow Imaging
• M-Mode Gray Scale Imaging
• Color M-Mode
• Doppler
• 4D (Realtime 3D, introduced 2004)
• Different combinations of the above modes
Vivid 7 is a digital beamforming system. Signal flow  travels from the Probe Connector Panel to the Front 
End Electronics, then to the Back-End Processor, an d finally, the results are displayed on the monitor
System configuration is stored  on the hard drive (inside the Back-End Processor (BEP)) and all 
necessary software is loaded from the hard drive on power up.
A Physio module, the Patient I/O,  is incorporated in the Back-End Processo r (BEP) to provide ECG 
signals to synchronize cardiac ultrasound image acqu isition. Other analog signals, from devices such 
as treadmills (e.g. ECG an d phono), are also processed by the Patient I/O.

Chapter 5 - Components and Functions (Theory) 5 - 3
5-2-2 Signal Flow
The TX board(s) in the Front-End Processor, generat es the strong bursts transmitted by the probes as 
ultrasound into the body. The Transmit bursts are rout ed from the TX board via the XD bus to the Relay 
board where the ultrasound probes are connected.
Weak ultrasound echoes from blood cells and body st ructure are received by the probes and routed via 
the Relay board and the XD bus to the RX board. The RX board amplifies these signals and converts 
them to a digital signal.
After amplification and digital signal processing in the  Front-End electronics, the signal is transferred via 
the PCI bus to the Back-End Processor where the signal is converted to video.
The video signals are connected to the monitor, to  the Cassette Video Recorder (VCR) and the internal 
video printers. The signals are also converted  so they can be connected to Digital Printers.
5-2-3 System Configuration and Software
System configuration is stored on a hard  disk drive inside the Back-End Processor.
At power up, all necessary software is loaded from the hard disk.
5-2-4 Operator Panel
The user initiates system operation via the Operator Panel which contains an alphanumeric keyboard 
and a control panel with controls for TGC and the LCD displays. 
5-2-5 The Electronics
Vivid 7 internal electronics are divided into two card cages;
• Front-End Processor (FEP)  The FEP is sometimes called “Front-End Card Cage” or only “Card Cage”.
• Back-End Processor (BEP)
Interconnecting signals and power distribution between the different modules are routed via the 
backplane, via cables, via the Internal I/O and the External I/O.
