4.10 RCV and XMIT BNCs
The two transducer BNCs (RCV and XMIT) are connected together when the Pulse Echo
mode of operation is selected. A single element transducer may be connected to either BNC
with the same results.
For Dual and Through transmission modes of operation, the transducer excitation pulse is
present at the XMIT BNC only. A fixed 100V load is connected to the RCV BNC in these
modes. The RCV connector monitors the return echoes from the dual element transducer. The
damping control is connected to the XMIT BNC only.
Poor quality or excessively long cable, while not detrimental to the instrument, can
adversely affect signal-to-noise ratio. For best results, use quality cables no longer than
necessary for the operation.
