Installation Manual
10.1.2 Commissioning Step 2: Channel Gain
Start the BTxR and run the WASSP program. See “7.4 WASSP Software Operation” on
page 26. With the BTxR ON, configured and connected correctly, the system should
now be ready to acquire data.
Ensure the transducer is submerged
in water.
Click the
Transmit Mode
button to begin pinging.
On the
Menu Task Bar
, set the
Range Knob
to manual (double click switches between
auto and manual, manual being yellow) and set to show seafloor .
Open the
Remote Diagnostics
window. Refer to Section “15.1 Open Remote
Diagnostics Utilities” on page 68
The
Bar Graph
tab is used to diagnose issues with the transducer and wiring. Major
problems with any of the receiver channels should be easy to spot using this facility.
See “Figure 35. I/Q Bar Graphs showing Good Reading” on page 42. As the data
comes in throughout the duration of a ping, the display instantly changes. The I channel
is displayed in
GREEN
, the Q channel is displayed in
RED
and magnitude in
YELLOW
.
The letters along the lower axis are directly linked to the respective 26 channels on
the receiver board and the transducer elements. The slider bar to the right of the bars
controls the gain of the display.
Use the slider bar on the side of the box to adjust the bars so that they fill about a third
of the form height. Ensure there are no extreme (more than 200%) changes in signal
strength across the channels. The display should update regularly and the values
should fluctuate, If one or more bars are full ON or full OFF there is a problem that you
need to resolve before continuing.
The source of problems identified in this test is most likely to be in the connections from
the transducer cable into the BTxR receiver board. If a wire/connector is loose or has
lost some of its insulation you will likely see a blank or very high channel. See “Figure
36. I / Q Bar Graphs showing problems” on page 42 .
If the I/Q Bars window is blank
then the system is not acquiring
sonar data. Check that the system
is pinging.
