Raw variables derived from Simrad data files

This page describes the variables that Echoview can derive from data files logged by Simrad echosounders.

Legend

s = the sensor number

t = the transducer number

n = the channel number

H = H-mode pings

V = V-mode pings

Notes:

  • Simrad is a subsidiary of Kongsberg. See also Raw variables derived from Kongsberg data files.
  • The variables that are derived from any given data file will depend on the transducer type and transducer calibration used during logging.
  • Vessel logs can be derived from some data files. They can be:
    • used as the source of distance for time/distance grids,
    • used as the source of distance for school detection, and
    • included in exported data, see About analysis variables.
  • Sv raw pings, TS raw pings and angular position raw pings may all be multiplexed by users with specific hardware. Multiplexed variables will have (channel c) appended to their name - where c is the channel number. See Multiplexed variables.
