Constant Multiply

This operator multiplies a variable by a constant number that is specified on the Constant page of the Variable Properties dialog box.

dB values are multiplied as dB values (e.g. -70dB x 10 = -700 dB).

Echoview accepts a single operand of the following data types as input:

  • Color
  • Linear
  • Multibeam color
  • Multibeam magnitude
  • Multibeam Sv
  • Multibeam TS
  • Multibeam unspecified dB
  • Power dB
  • Sv
  • TS
  • Unspecified dB



The Constant Multiply Variable Properties dialog box pages include (common) Variable Properties pages and these operator pages:

The calculation is applied within the domain of the data type. That is, dB calculations in the dB domain and linear calculations in the linear domain etc.
