Calibrating for Noninsertable Devices
Calibrating for Noninsertable Devices
Modify the Cal Kit Thru Definition
With this method, it is only necessary to use a thru adapter. The calibration kit thru
definition is modified to compensate for the adapter and then saved as a user kit. However,
the electrical delay of the adapter must first be found. The adapter match will degrade the
effective load match terms on both ports as well as degrade the transmission frequency
response (tracking).
1. Refer to Figure 4-3 (or Figure 4-4) while performing the steps in this procedure. Also
refer to the “Adapter Removal” subsection (part of the “Calibrating for Noninsertable
Devices” section) for an explanation of A1, A2, and A3.
2. Perform a 1-port calibration at “Reference Port 1.” Refer to Step A of Figure 4-3 (or
Figure 4-4).
