uW_cal_define_standard - define the set of parameters for a SOLT standard such as C0 for the "open" standard.

Calling Sequence

standard=uW_cal_define_standard(type,value[,value2,...])

Parameters

Description

This function generates a tlist which contain all the data of a calibration standard in order to use this information with " uW_cal_standard " function. This function can include delay or losses informations. Those data must appear in the input parameter as a string. Notice that the offset is NOT a parameter. If your Calkit is described with an offset, please convert it in a delay before using this function with " uW_cal_mm2s ".

Examples


// Cascade ACP40-A-GSG-100 "Open" definition
// C0 = -9.30 fF
open=uW_cal_define_standard("O",-9.3e-15);

// You can acces to data as follow :
typeof(open)
open.C0

// Calculate the S11 from those data :
f=2*10^9;  // f=2 GHz
S11=uW_cal_standard(f,open);

// ========================================
// Example with with 12ps delay and no loss
// C0 = 5e-15
// C1= 60 e-27
// C2 = -11 e-36
// C3 = 0.41 e -45

open=uW_cal_define_standard("O",5e-15,60e-27,-11e-36,0.41e-45,'delay=12e-12','loss=0');

// Now you can check the values as follow :
open.C2

// Read the delay
open.delay
