Spectrogram and Topographic Markers

Description

function is particularly useful as it allows you to make delta measurements
both in the frequency and time domain.

Marker and turn on.
When in the Spectrographic view (single or split screen), press

position (frequency).
Press Y Axis[F2] and the set the y-axis position (amplitude).

The frequency and amplitude information will be displayed on the
remaining function keys:
