7-3-9-2 Normal Channels Diagnostic Tests
Tests the output channels from the input channels. This test setting is used for all modes, except
CW-Mode.
The Normal Channels Diagnostic Tests check each amplifier output against the predefined output level.
This system test is performed in Phased Array Probe Simulation mode. The FEC board injects analog
signals to the Tx amplifiers inputs after the Tx switch. The test lasts approximately 4 minutes.
Note: System re-boot is required if the tests are not being performed in the sequence described in
Section 7-3 "Performing Front End (FE) Diagnostics" on page
1) Disconnect all the probes.
2) Access the F.B. tab of the FE Diagnostics dialog box, as described in
Board Assembly Options" on page
3) Trackball to Pulser 1 (High Voltage Power Supply [HVPS] +/-80V) or Pulser 2 (Low Voltage Power
Supply [LVPS] +/-40V) and press Select.
Trackball to the Normal Channels Test button and press Select. The normal channels diagnostic test
is performed, and the test results are displayed in the Report dialog box, as shown below:

Normal channels: Test the output channels from the input channels, as described in
Channels Diagnostic Tests
Expanded low channels: Tests output signals in CW-Mode only, when the input channels are
connected to the output channels, as described in
Tests" on page 7-57.
Expanded high channels: Tests the output signals from the input of the high channels, as
described in 7-3-9-4 "Expanded High Channels Diagnostic Tests" on page
Port Test: Performs a general logic test, as described in
