Group delay
Group delay is computed by measuring the phase change within a specified ape rture (for aperture see
GD [s] =
Phase change [deg] (Equation
1)
Aperture [Hz] *
360
相位不确定度 [±deg]
* sqrt(2) (Equation

Aperture [Hz] *
360
Determined by the frequency span and the number of points per sweep:
Aperture: (frequency span) / (number of points–1)
GD Range
The maximum group delay is limited to measuring no more than
± 180 degrees of phase change within
the selected aperture (see Equation
1).
