A. Direct Connection Type Test Fixture

This section describes the calibration procedures to follow when a direct connection type test fixture is connected to the four-terminal pair port of the E4990A and a device is connected to the test fixture contacts.

Direct connection type test fixtures include:

• 16034E Chip component test fixture

• 16034G Chip component test fixture

• 16034H Chip component test fixture

• 16044A Chip component test fixture

• 16047A Lead component test fixture

• 16047D Lead component test fixture

• 16047E Lead component test fixture

Although the following test fixtures have cables, their calibration must be performed in the same way as a direct connection type test fixture:

• 16065A External DC Bias Fixture

• 16089A Kelvin Clip Lead

• 16089B Kelvin Clip Lead

• 16089C Kelvin Clip Lead

• 16089D Alligator Clip Lead

• 16089E Kelvin Clip Lead

Perform the fixture compensation in accordance with Fixture Compensation.

• When you use a direct connection type test fixture, neither user calibration nor port extension compensation is required for measurement (they cannot be performed).
