Signal transmission check - ringing
To verify correct signal transmission from the SBP transceiver to the TX transducer
elements a signal transmission check, often referred to as ringing, can be done. The
principle is to use a test transducer and a signal generator to induce a signal from each of
the transducer elements and verify the reception at the transceiver.
Note
The test transducer element may be any unit that by using a signal generator transmits
at the relevant frequency.
The SBP 29 TX elements can be used for this purpose. We suggest that you mount all
TX elements but one, use the last element for the signal check, and mount it when test
is completed.
How to verify the signal transmission
1
Position the test transducer element against one the transducer element to induce
a signal
2
Determine from illustration referred below, what channels (pins) at the transceiver
cable connector
3
Observe the received signal at the transceiver cable connector using a oscilloscope
4
Verify that the signal is received at the correct channels (pins) at the correct
transceiver cable connector
5
Repeat for each TX element
The signal path to verify is shown in the following illustration
