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 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:
or
. Toggle to ON.
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.
