E. Calibration When the 7-mm Port of the 42942A is Extended

In measurements using the 4294A, the electrical length (delay time) of a 42942A dedicated

test fixture (such as 16092A) and 42941A's dedicated probe adapter can be regarded as 0.

Step 4. Perform fixture compensation at the device contacts of the test fixture. See "Fixture

Compensation" on page 151 for the fixture compensation procedure.

If user calibration in step 2 cannot be performed for some reason, set the port extension

value in electrical length or delay time, which is equivalent to the electrical length between

the 7-mm port of the 42942A and the device contacts of the test fixture, in place of steps 2

and 3, in accordance with "Port Extension Compensation" on page 150.
