The delay calculation is based on the already measured sweep points and does not
slow down the measurement.
Δf is constant over the entire sweep range, if the sweep type is a Lin. Frequency
sweep. For Log. Frequency and Segmented Frequency sweeps, it varies with the
sweep point number m.
Application:
The aperture must be adjusted to the conditions of the measurement. A
small aperture increases the noise in the group delay; a large aperture tends to mini-
mize the effects of noise and phase uncertainty, but at the expense of frequency reso-
lution. Phase distortions (i.e. deviations from linear phase) which are narrower in fre-
quency than the aperture tend to be smeared over and cannot be measured.

Default Marker Frmt
Defines the default marker format of the active trace. "Default" means formatted
according to the selected trace format.
New markers will be formatted with the trace's "Default Marker Frmt" ; existing markers
will be reformatted if (and only if) their
