Quick Start: Learning How to Make Measurements

Learning to Make Reflection Measurements

Step 1. Choose measurement parameters with your test device connected

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

2.Connect your test device as shown in Figure 2-8.If using a load, make sure it has the correct characteristic impedance.

CAUTION Damage may result to the device under test 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.

3.Choose the following measurement parameters:

Meas Refl: FWD S11 (A/R) or REFLECTION

Center200 M/μ

Span375 M/μ

Power 5x1

Scale Ref AUTO SCALE

4.Look at the device response to determine if these are the measurement parameters that you want. For example, if the trace is noisy you may want to increase the input power, reduce the IF bandwidth, or add averaging. To better see an area of interest, change the test frequencies.
