Verifying system operation by means of the Element BITE
functionality
The purpose of the
Element BITE
(Element Built-In Test Equipment) dialog box is to allow
on-line test and verification of the individual elements in the transducer. It allows you to see
if the transducer elements are operational during transmission and reception. The
B-Scan
page allows you to monitor the data received from each of the elements in the transducer.
The start sample and the number of samples to be displayed are selectable.
Prerequisites
The MF90 system hardware units are installed as specified in this manual.
• The MF90 system is turned on and operates normally.
• The MF90 system is in Normal mode, but
TX Power
is set to Off to prevent transmissions.
• The transducer is retracted to its upper position.
• The vessel is berthed or at sea.
Caution
You must never set the MF90 system to "ping" unless the transducer is submerged in water.
The transducer may be damaged if it transmits in open air.
Neither tools nor instruments are required.
Context
By means of the
Element BITE
(Element Built-In Test Equipment) functionality, you can
easily determine if the MF90 hardware is operational. The following pages are provided:
Matrix
The
Matrix
page allows you to monitor the average signal values or signal phases from
each of the channels and transducer elements in the MF90 system. The presentation is
provided on a matrix corresponding to the element locations in the transducer.
B-Scan
The
B-Scan
page allows you to monitor the data received from each of the elements
in the transducer. The start sample and the number of samples to be displayed are
