Completion Menu Buttons
For this example menu, the Port 1 Reflective Devices to the Isolation (Optional) buttons link to completion submenus where additional calibration procedures are performed.
For example, the Port 1 Reflective Devices button (shown below at #1) links to the REFL. DEVICES PORT 1 submenu. As each procedure is completed, the submenu button is marked with a completion checkmark. When all the procedures on the submenu are completed, use the Back button to return to the FOUR PORT CAL menu.

Kit Info Button
Select displays the STANDARD INFO or USER DEFINED STANDARD dialog box for the selected connector and calibration method that displays the connector calibration coefficients. The dialog box contents depend on the selected connector, Cal Method, and Line Type. The examples show typical standard information dialog boxes.
• Since the STANDARD INFO (mSSS) dialog derives from the SSS calibration kit definition, three shorts are available and the one to be used for the current line in the mSSS table is defined by the Select Short to use field. All of the shorts in the kit can be employed in the mSSS calibration, but each must be assigned to a separate line in the table.
This field (in conjunction with the @Frequency field and the offset length) is used to compute the loss in the short and hence the magnitude of its reflection coefficient. This is mainly relevant for very large offset lengths (> 10 mm) at microwave frequencies or somewhat shorter lengths at millimeter wave frequencies.
@Frequency (GHz)
This field (in conjunction with the loss in dB/mm and the offset length) is used to compute the loss of the offset short (and hence the magnitude of its reflection coefficient) at each frequency. If a non-zero value is entered here, it is treated as the reference frequency fref at which the loss (dB/mm) was defined and the loss at all other frequencies is scaled by sqrt(f/fref). If 0 is entered here, the loss is assumed to be constant with frequency.
Use Match Checkbox
When this box is checked, a match measurement is acquired during the calibration and is used whenever even the collection of offset shorts does not have enough phase separation (value defined within the USER DEFINED MATCH dialog: Electrical line length delta for match use, expressed in degrees). The decision to use the match data is made on a frequency-by-frequency basis. See the MS464XB Calibration and Measurement Guide for more information. This helps increase bandwidth of the calibration, particularly at lower frequencies, if a match standard is available.
When this box is checked, more weight is given to those offset shorts that contribute most to large electrical length deltas and hence to bandwidth of the calibration. More details can be found in the MS464XB Calibration and Measurement Guide. Using this feature can increase the available bandwidth of the calibration, but does reduce immunity to repeatability variances in the setup, so it is not advised in more repeatability challenged scenarios (e.g., fixtures where the short standards are attached by spring force alone).
