Adjusting The Output Power; Adjusting The Pulse Duration - Simrad ES80 Reference Manual

Simrad ES80 Reference Manual

Adjusting the output power

You are permitted to adjust the output power of the ES80. You can not increase the
power to beyond the transducer's capacity, but you may reduce it for better performance
in shallow water, or if you are struggling with reverberation.
Context
The parameter in the
Power
output power measured in Watts. You can change the output power manually. Output
power is limited either to the maximum rating of the transducer, or the maximum rating
of the transmitter, whichever is the smallest. For all practical purposes, this means
that you can reduce the power output, but you can not increase it to beyond the power
rating of the transducer.
The current setting of this parameter is also shown in the
Note
The settings in the
Normal Operation
transducer setup file. You can therefore not make any changes that might damage your
transceiver or transducer. Certain settings may be limited by your license. Do not to
make any changes unless you are well aware of the consequences.

Adjusting the pulse duration

The setting specifies the current duration ("length") of the transmitted
Pulse Duration
pulse. You can manually select a pulse duration that suits your operation. You can
also choose automatic duration.
Context
The pulse duration can be adjusted according to the current depth and what kind of fish
you are looking for. The deeper you wish to see, the longer pulse duration should be
used. Remember that in the ES80, the pulse duration and the bandwidth are mutually
dependant.
