MARKERS: COUPLED
couples the

display
channels.
Even if
the stimulus
is
uncoupled
and
two
sets
of

values
are
shown,
the

track the
same
stimulus
values on each channel as long as they are within the displayed
stimulus range

MAXIMUM FREQUENCY
is used to dene the highest frequency at which a calibration
kit standard can be used during measurement calibration. In
waveguide, this is normally the upper cuto frequency of the
standard.
