Show All Raw Multi-Channels


Macros: MultiAll

By default, Multi-Channel Output mode only displays signals from the active channels designated as Left [L] and [R] on their Monitor As buttons. These appear as normal stereo Left and Right displays, and can likewise be averaged, shown as spectrograms, used as Trigger Sources, or viewed in Decimate mode.

When the Show All Raw Chans button is depressed, all active channels are displayed. Those selected as Monitor As Left and Right will continue to be processed as above for averages or trigger sources. However, they will be displayed using a fixed format such that the color corresponds to the Left or Right label of the channel regardless of how it is used via Monitor As.

Assuming the default Left and Right output colors of green and violet:

    Front Left      ----- Green   (solid)
    Front Right     ----- Violet
    Center          - - - Green   (dashed)
    Low Freq        - - - Violet
    Back Left       ..... Green   (dotted)
    Back Right      ..... Violet
    Side Left       .-.-. Green   (dot-dash)
    Side Right      .-.-. Violet

The channel traces will be superimposed by default unless the Spacing control is used to separate them.

Multiple traces (other than the two selected for monitoring as Left and Right) will only be seen in raw (unaveraged) waveform or Spectrum modes. They will not be seen when Decimate is active.
