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