Table 1 Test hydrophone data

For measurement of the source level in OMNI, use the following

menu settings:

RANGE......: 175M

MODE.......: BOW UP

PULSEFORM..: CW-NORMAL

TX POWER...: FULL

PINGSECTOR.: OMNI

Connect the hydrophone and TX ENABLE pulse to the

oscilloscope as shown in figure 14. Note that an optional cable

with connectors for the TX ENABLE pulse can be ordered from

Simrad.

As indicated in the figure, the distance between the transducer

and the hydrophone should be approximately 5 - 10 meters.
