Math Functions Support 'NoValue'

  • In math channels you can use “NoValue” to supress any output in WinDarab (e.g. the oscilloscope signal is interrupted).
  • A math function “IsValue” was added to checka input value for “NoValue”.
  • Also, all analysis windows (should) work correctly if they meet a “NoValue”.
  • Note: All comparisions with NoValue will returns false (NoValue is internally a NaN double value)
  • Here’s a sample math function:

if (nmot > 6000; nmot; NoValue)

This channel will show only a signal, if nmot is larger than 6000 – anywhere else there’s nothing!
