Adapter Removal Using ECal (ES Analyzers Only)
Adapter Removal Using ECal (ES Analyzers Only)
A device under test (DUT) whose connectors cannot be connected directly to a test
configuration is considered to be a noninsertable device. See Figure 4-12 (or Figure 4-13).
Noninsertable devices can be caused because the DUT has:
• input or output connectors with the same sex connector as the test configuration.
• input or output connectors of a different connector type than the test configuration.

The adapter removal calibration technique may be used with the ECal calibration to
accurately measure noninsertable devices. The following adapters (shown in Figure 4-14
or Figure 4-15) are needed.
