skrf.frequency.Frequencyļ
 class skrf.frequency.Frequency(start=0, stop=0, npoints=0, unit=None, sweep_type='lin')[source]ļ
A frequency band.
The frequency object provides a convenient way to work with and access a frequency band. It contains a frequency vector as well as a frequency unit. This allows a frequency vector in a given unit to be available (
f_scaled
), as well as an absolute frequency axis in āHzā (f
).A Frequency object can be created from either (start, stop, npoints) using the default constructor,
__init__()
. Or, it can be created from an arbitrary frequency vector by using the class methodfrom_f()
.Internally, the frequency information is stored in the f property combined with the unit property. All other properties, start stop, etc are generated from these.
