Group Delay
Chafacterirticr
Group delay is computed by measuring the phase change within a specified
frequency step (determined by the frequency span, and the number of points
per sweep).
Aperture:
Maximum aperture: 20% of frequency spun
Minimum aperture: @requency span) /(number of points - 1)
Range:
The maximum delay is limited to measuring no more than 180” of phase
change within the minimum aperture.
Range = l/(2 x minimum aperture)
Accuracy:
The following graph shows group delay accuracy at 1300 MHz with
type-N transmission calibration and 15 Hz lF’ bandwidth. Insertion loss is
assumed to be ~2 dB and electrical length to be ten meters.
