turns on the display of visible
measurement indicators for measurement 2.
MEASUREMENT:
INDICATORS:STATE?
might return

indicators are active.
MEASUremen
t:INDICators:VERT<x>? (Query Only)
Returns the value of the specified vertical measurement indicator <x> from the
trigger point, where <x> can be 1 through 8. A negative value means that the
indicato
r is positioned earlier in the waveform record than the trigger point.
