The data exports to Matlab, and data analysis, signal processing and classification scripts are provided with the instrument. The sonar system and processor exist in a single unit and it comes with a 30m cable with an extension to 100m available. The 2100B has a 6 degree conical beam operating at a frequency of 135 -200 kHz as a sweep waveform. It has a spatial resolution of 1.2cm."@en ; sdo:inDefinedTermSet ; sdo:name "Scientific Fishery Systems SciFish 2100 B (Broadband) echosounder"@en ; sdo:termCode "SDN:L22::TOOL1443" .
