7-8-3-10 Image Port Test When selecting the ImagePort Test, the scanner issues a test command to the local software running 
on the I960RP processor on the Image Port board. 
The test command will start the following tests;
• test the interrupt based command/replay mechanism
• reset the ImagePort board
• test the PipeLink data fifo
• test the video data fifos
• test the PipeLink control fifo
• test the video control fifo
• test the video grabber chip
Results;
• Green light: - OK
• Red light: - Failed
7-8-3-11 Chain (Signal Chain, RLB/RX/BF Test) NOTE: A Test Attenuator, Part Number  AA200215 is needed for this test.
Remember to restart the Vivid 7 after the diagnostics session.

Chain Signal Chain Test (Chain)
The Signal Chain/ Data Flow test checks for er
rors in the TX, RLY, RX and BF chain of data 
flow.
Te s t  A l l Not Used.
TX/RLB/RX/ BF Tests data flow in Front-End Transmit Receive signal chain.
If an error occurs with this test, testing 
should be continued in the following order;

7 - 74 Section 7-8 - Acquisition Diagnostics
7-8-4 General Recommendations  to Troubleshoot Noise Issues
Ultrasound machines are susceptible to Electromagne tic Interference (EMI) from radio frequencies, 
magnetic fields, and transients in the air or wiring.  They also generate EMI. The Vivid 7 complies with 
limits as stated on the EMC label. Ho wever there is no guarantee that interference will not occur in a 
particular installation. 
Possible EMI sources should be identified before the unit is installed. 
Electrical and electronic equipment may produce EMI un intentionally as the result of a defect. Some of 
these sources include:
• medical lasers
• scanners
• cauterizing guns
• computers
•monitors
•fans
• gel warmers
• microwave ovens
• light dimmers 
• portable phones
The presence of a broadcast station or br oadcast van may also cause interference.

7-8-5 EMI Prevention/abatement
     
Table 7-12    EMI Prevention/abatement
EMI RULEDETAILS
BE AWARE OF RF 
SOURCES
- Keep the unit at least 5 meters (15 feet) away from other emi sources. 
- Special shielding may be requi
red to eliminate interference problems caused by high frequency, 
- High powered radio or video broadcast signals.
GROUND THE UNIT - Poor grounding is the most likely 
reason a unit will have noisy images. 
- Check grounding of the power cord and power outlet.
REPLACE ALL SCREWS, 
RF GASKETS, COVERS, 
CORES - After you finish repairing or updating the s
ystem, replace all covers and tighten all screws. 
- Any cable with an exter nal connection requires a magnet wrap at each end. 
- Install the card rack cover over the card rack. 
Loose or missing covers or RF gaskets allow  radio frequencies to interfere with the ultrasound 
signals.
REPLACE BROKEN RF 
GASKETS- If more than 20% or a pair of the fingers on an rf gasket are broken, replace the gasket. 
- Do not turn on the unit until any  loose metallic part is removed.
DO NOT PLACE LABELS 
WHERE RF GASKETS 
TOUCH METALNever place a label where rf gaskets meet the uni t. otherwise, the gap created will permit rf leakage. 
or, if a label has been found in such a position, move the label.
USE GE SPECIFIED 
HARNESSES AND 
PERIPHERALS- The interconnect cables are grounded and r equire ferrite beads and other shielding. 
- Also, cable length, material, and routing are all  important; do not change from what is specified.
TAKE CARE WITH 
CELLULAR PHONES Cellular phones may transmit a 5 v/m signal
; that could cause image artifacts. 
PROPERLY DRESS 
PERIPHERAL CABLES Do not allow cables to lie across the top of t
he card rack or hang out of the peripheral bays. Loop 
the excess length for peripheral cabl es inside the peripheral bays. attach the monitor cables to the 
frame.

NECESSARY ESD PRECAUTIONS: 
ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP, TO THE ADVISED ESD 
CONNECTION POINT LOCATED AT THE REAR  OF THE SCANNER (TO THE RIGHT OF 
THE POWER CONNECTOR). 
FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC SENSITIVE 
EQUIPMENT.
