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