Performance specifications
These performance specifications summarize the main functional and operational characteristics of the CS90 Fish Finding Sonar.
Operational frequency
•  User selectable: 70 to 90 kHz in steps of 1 kHz
Operational range
•  Range steps (Standard)25 to 2000 m
Even though you can choose a large range value, that does not mean that you can detect your targets on the same range. The range value only defines the range that is shown in the views. Actual target detection will always depend on the operational environment, such as water temperature, salinity, interference and layers in the water column.
Tilt function
•  Horizontal transmissions ("Pings")-10 to +84 degrees
•  Vertical transmissions ("Pings")Fixed 43 degrees
•  Plane transmissions ("Pings")-10 to +84 degrees
Transmission
•  Number of transmitter channels: 480
•  Transmission sectors (Horizontal views):
–  MaximumOmni
–  Sectors30, 60, 90, 120, 180 degrees plus Omni
•  Transmission sectors (Vertical views):
–  Maximum120 degrees
•  Transmission sectors (Plane views):
–  Sectors30, 60, 90, 120, 180 degrees plus Omni
•  Pulse forms:
–  CW (Continuous Wave) transmissions
–  HFM (Hyperbolic Frequency Modulation) transmissions (This pulse type is also known as "chirp".)
Reception
•  Number of receiver channels480
•  Gain functions:
–  TVG (Time Varied Gain)
–  AGC (Automatic Gain Control)
–  RCG (Reverberation Controlled Gain)
•  Digital filters:
–  Ping-Ping Filter
–  Noise Filter
–  FM Correlation filter
–  Bottom Filter
Echo presentations
•  Display resolution: 1280 x 1024 pixels (Minimum)
The visual quality of the CS90 presentation depends on the quality of your graphic adapter and display. We recommend that you use a large display with resolution 1920 x 1080.
•  Colours: A selection of echo colours is available to fit your presentation preferences. Each selection represents a dedicated colour scale.
•  Palettes: A choice of colour palettes is available to fit ambient light conditions.
Beamwidths
•  User selectable: Narrow, Normal or Wide
Stabilisation
•  Roll stabilisation±20 degrees (Automatic)
•  Pitch stabilisation±20 degrees (Automatic)
•  External stabilisation sensor: Interface to an optional peripheral motion reference unit (MRU) is supported The CS90 has been designed to match the motion reference unit (MRU) sensors manufactured by Kongsberg Seatex.
Interfaces
•  Interfaces to peripheral devices: Serial lines + Ethernet (LAN) line
•  Transceiver Unit: Ethernet (LAN) line
User interface
•  Main control: The Operating Panel offers all necessary control functions for normal operation of the CS90.
•  Secondary control: A comprehensive menu system allows access to all CS90 functionality.
•  Optional control: You can also use a standard computer mouse to control the CS90. The mouse can be connected to either the Operating Panel or directly to the Processor Unit.
•  Menu languages: The text in the menu buttons in the CS90 user interface can be provided in several different languages. With a few exceptions, the chosen language is also used for all other texts.
