Parameter: Trace amplitude ref


Full name: Offset to trace amplitude reference point
Units: sec or per
Range: [ -1 p, 2 gp ]
Initial value: -1 p

Affects: all trace amplitude graphs

Trace amplitude measurements are taken on each frame as the difference between the level at a sample point, and the level at this reference point.

This parameter can be set by specifying the time offset from the start of the sweep. It can also be set visually, using the pointing device to indicate the time on the displayed sweep for the reference point (and the sample point).

If the "Trace amplitude ref" option is set to a negative value (e.g. -1p), then the reference level is not measured, and the sample level is taken as an absolute reading.
