edges_cal.reflection_coefficient.CalkitStandard
- class edges_cal.reflection_coefficient.CalkitStandard(*, resistance, offset_impedance=<Quantity 50. Ohm>, offset_delay=<Quantity 30. ps>, offset_loss=<Quantity 2.2 GOhm / s>, capacitance_model: ~edges_cal.modelling.Polynomial | None = None, inductance_model: ~edges_cal.modelling.Polynomial | None = None)[source]
Class representing a calkit standard.
The standard could be open, short or load/match. See the Appendix of Monsalve et al. 2016 for details.
For all parameters, ‘offset’ refers to the small transmission line section of the standard (not an offset in the parameter).
- Parameters:
resistance (float | astropy.units.quantity.Quantity) – The resistance of the standard termination, either assumed or measured.
offset_impedance (float | astropy.units.quantity.Quantity) – Impedance of the transmission line, in Ohms.
offset_delay (float | astropy.units.quantity.Quantity) – One-way delay of the transmission line, in picoseconds.
offset_loss (float | astropy.units.quantity.Quantity) – One-way loss of the transmission line, unitless.
