7-3-8-2 Transmit Test
If a solid dark line is observed during scanning, it may indicate a bad transmitting channel. The transmit
test checks the FE pulsers via the probe elements, enabling you to check the transmitting channels. The
transmit test is not sensitive to the receiving channels.
Note: To avoid irrelevant failure results, it is imperative that the probe used to perform the transmit
test is in good condition.
1) Connect either a 7S or 3S probe and lock it in place.
2) Access the F.B. tab of the FE Diagnostics dialog box, as described in the Accessing the Front Board
Assembly Options section, on page 7-26.
3) In the Select Socket area of the F.B. tab, trackball to the socket to which the 7S or 3S probe is
connected:
• Trackball to Left, Right or Center and press Select.
4) Trackball to Pulser 1 (High Voltage Power Supply [HVPS] +/-80V) or Pulser 2 (Low Voltage Power
Supply [LVPS] +/-40V) and press Select.
5) Trackball to the Transmit Test button and press Select. The transmit test is performed and the test
results are displayed in the Report dialog box, as shown below:
