4.3.4 (Ping) Max Rate
The max (ping) rate setting allows the operator to set the number of pings
per seconds. The actual number of pings depends on the current range
setting.
Figure 4-21
(Ping) Max Rate
The normal value for the ping rate is the maximum rate to be sure that
always the highest possible ping rate, depending on the range setting,
can be achieved.
In some instances it may be beneficial to force a lower ping rate than the
normal rate associated with a particular range. Examples of this would be
instances when the vessel is moving at a very slow rate, and the operator
wants to reduce the quantity of data that is generated; or when the sonar
is operating in a high-reverb environment where echoes of the previous
ping are contaminating the current ping.
4.3.5 Frequency
For a dual-frequency system, the frequency setting allows the operator to
switch the frequency on the fly without restarting the 7K Center. All sonar
controls will then be dedicated to the selected frequency.

Frequency
The addition of the dual-frequency system is that the lower frequency
provide a long-range functionality and the higher frequency a high-
resolution functionality with a shorter range.
4.3.6 Beam width
For some sonar types (e.g. the 7160) it is possible to change the along
track width of the beam.

Beam Width
4.3.7 Pulse Type
The pulse type setting allows the operator to choose between CW
(Continuous Wave) and FM (Frequency Modulation).
Figure 4-24
Pulse type
The possibility to choose CW or FM depends on the sonar system.
