Moving in the table of calibration standard definitions (see figure) using navigation keys. Enter the parameter values for a calibration kit by using the navigation keys in the table of calibration standard definitions:
Standard Type |
Select the standard type: •Open •Short •Load •Thru •Data-Based |
Standard Label |
Standard labels specified on the calibration menu softkeys. |

For an OPEN standard, C1 coefficient in the polynomial formula of the fringe capacitance. |
C2·1e-36 F/Hz2 |
For an OPEN standard, C2 coefficient in the polynomial formula of the fringe capacitance. |
C3·1e-45 F/Hz3 |
For an OPEN standard, C3 coefficient in the polynomial formula of the fringe capacitance. |
L0·1e-12 H |

For a SHORT standard, L2 coefficient in the polynomial formula of the residual inductance. |
L3·1e-42 H/Hz3 |
For a SHORT standard, L3 coefficient in the polynomial formula of the residual inductance. |
Offset Delay, ps |
Offset delay value in one direction (ps). Can be switched to physical length (mm). The parameter is used only for the calibration standard model. |
Offset Z0, Ohm |
Offset characteristic impedance value (Ohm). For waveguide must be set to 1 Ohm. |
Offset Loss, GOhm/s |
Offset loss value (GOhm/s). The parameter is used only for the definition of the standard with the help of the calibration standard model. |
F min, MHz |
Minimum operating frequency of the coaxial standard. Lower cutoff frequency of the waveguide standard. |
F max, MHz |
Maximum operating frequency of the coaxial standard. Upper cutoff frequency of the waveguide standard. |
Media |
Coaxial or Waveguide |
H/W |
Waveguide height to width ratio. |
Calibration standard type and label editing
To set the type of a standard, double click on the field with the name of the standard in the Standard Type line and select the type in the opened Standard Type dialog: •Open or Short or Load or Thru — if the standard is described with an equivalent circuit. •Data-Dased — if the standard is described with the Table of S-parameters (See Calibration Standard Defining by S-Parameter File). To edit the label of a standard, double click on the field in the Standard Label line and enter a description for the standard using the on-screen keypad. To save the settings and close the dialog click Ok.

Calibration standard parameters editing
To edit the calibration standard parameters, and double click in the table on the corresponding cell. Enter the required value using the on-screen keypad.
|
Calibration Standard Defining by S-Parameter File
Parameters of a calibration standard can be set from an S-parameter file in Touchstone format (See Data-Based Calibration Standards).
To set the calibration standard parameters by S-parameter file double click in the table on the corresponding field in the Touchstone File line. The table of S-parameters can be filled downloaded from a file of Touchstone format. Files with *.S1P extension are used for one-port standards, and files with *.S2P extension are used for two-port standards.
