skrf.frequency.Frequency

class skrf.frequency.Frequency(start, stop, npoints, unit='ghz', sweep_type='lin')

A frequency band.

The frequency object provides a convenient way to work with and access a frequency band. It contains a fruequency 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 frquency axis in ‘Hz’ (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 method from_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.
