The test fixtures are used to provide measurements that have high stability and repeatability. Keysight Technologies provides test fixtures for different sizes and types of SMDs (surface mounted devices) such as chip inductors and chip capacitors. The following test fixtures can be used with the E4991B:
16191A
16192A
16193A
16194A
16196A/B/C/D
16197A
This chapter describes measurement examples using a chip inductor of 1608 mm/0603 inches in size as the DUT and the 16197A as the test fixture.
The measurement example here requires the following equipment.
E4991B Impedance Analyzer
E4991B (main unit)
Test head
16195B calibration kit
Mouse
Keyboard
Keysight 16197A single-sided electrode SMD test fixture
16197A test fixture
Short device set
A pair of tweezers
Measurement DUT: Chip inductor [1608 mm/0603 inches]
Connect the test head to the E4991B. Be sure not to remove the four feet on the bottom of the E4991B when connecting the test head.
Do not connect the test fixtures to the test head at this point because calibration is performed on the DUT port (7-mm terminal) of the test head later.
Press the power switch to turn ON the power to the E4991B. The E4991B performs a power-on self-test. When the self-test is completed, the splash screen followed by the measurement screen appears on the LCD.
