Manual Calibration General Dialog Boxes - 2-Port VNAs
The dialog boxes displayed below are representative of standard and user-defined dialog boxes associated with the calibration function. Most of these dialog boxes can be called from multiple locations.
AIR EQUIVALENT LENGTH Calculator Dialog Box - 2-Port VNAs
Use the AIR EQUIVALENT LENGTH calculator dialog box to speed configuration of a thru line by entering its length in picoseconds (ps) and its dielectric constant. The calculator returns the air equivalent length in millimeters (mm).

Using the Calculator
1. Use the Enter length in ps (picoseconds) to input a length.
• For example, enter a value of 250 ps.
2. Use the Enter constant to change the dielectric constant as required.
• For example, change the dielectric constant to 1.2.
3. Click the Calculate Air Equivalent Length button.
4. The required value appears in the Air Equivalent Length in mm field.
• Using the examples above, an air equivalent length of 68.465319... appears in the field.
5. Click OK.
6. The Thru Info dialog box reappears with the calculated value in the Length (mm) field.
7. Using the examples above, the Length (mm) field displays 68.4653 mm.
