Quick Start: Learning How to Make Measurements

Measurement Procedure

Measurement Procedure

This is a general measurement procedure that is used throughout the guide to illustrate the use of the analyzer.

Step 1. Choose measurement parameters with your test device connected

Press the Preset key to return the analyzer to a known state.

Connect your device under test (DUT) to the analyzer.

CAUTION Damage may result to the DUT if it is sensitive to the analyzer's default output power level. To avoid damaging a sensitive DUT, be sure to set the analyzer's output power to an appropriate level before connecting the DUT to the analyzer.

Choose the settings that are appropriate for the intended measurement.

measurement type (S11 or reflection, for example)

frequencies

number of points

power

measurement trace format

Make adjustments to the parameters while you are viewing the device response.

Step 2. Make a measurement calibration

Press the Cal key to begin to perform a measurement calibration using a known set of standards (a calibration kit). Error-correction establishes a magnitude and phase reference for the test setup and reduces systematic measurement errors.

Step 3. Measure the device

Reconnect the device under test.

Use the markers to identify various device response values if desired.

Step 4. Output measurement results

Store the measurement file to a disk.

Generate a hardcopy with a printer or plotter.
