Making a Measurement
In this section, you learn how to execute the sampling measurements using the
4155C/4156C. As an example, you measure charge voltage of capacitor.
Measurement circuit and typical characteristics are shown below:
NOTE For accurate measurements, allow the 4155C/4156C to warm-up for a minimum of
40 minutes after you turn on the instrument, and then execute calibration. For the
self-calibration, see Chapter 7.
Step 1. Prepare for the measurement
Before executing measurement, configure the 4155C/4156C and Agilent 16442A
Test Fixture. See “Step 1. Prepare for the measurement” in “Making a
Measurement” in Chapter 1. The sampling measurement example uses the
connection same as the sweep measurement example connection.
Step 2. Mount your DUT on the test fixture
1. Select a suitable socket module for your DUT (capacitor).
2. Mount the socket module on the test fixture.
3. Mount the capacitor on the socket module.
4. Make connections with connection wires (miniature banana to pin plug etc.).
The capacitor must be connected between SMU1 and SMU2.
5. After finishing connections, shut the lid of the test fixture.
