Press the TRACE SELECT key in the TRACE keypad of the hardkey bar and use the
softkeys in the "Trace Select" menu if you wish to create a new trace or a new diagram
area.
2.1.2 Parameter and Sweep Range Selection
After preset the display shows a diagram with a dB Mag scale. The sweep range (scale
of the horizontal axis) is equal to the maximum frequency range of the analyzer, and
the S-parameter S
21
is selected as a measurement parameter.
To obtain information about the reflection characteristics of your DUT you have to
select an appropriate measurement parameter and specify the sweep range.
1. In the CHANNEL keypad of the hardkey bar, press START CENTER and enter the
lowest frequency you want to measure in the "Start Frequency" numeric entry bar
(e.g. 5 GHz).
2. Press STOP SPAN and enter the highest frequency you want to measure in the
"Stop Frequency" numeric entry bar (e.g. 5.5 GHz).
3. In the TRACE keypad of the hardkey bar, press MEAS and select the forward
reflection coefficient S
11
as a measurement parameter.
4. In the TRACE keypad, press SCALE and activate the "Autoscale" function. The
analyzer adjusts the scale of the diagram to fit in the entire S
11
trace, leaving an
appropriate display margin.
Tip:
Refer to
chapter 2.3.2, "Scaling Diagrams"
on page 33 to learn more about
the different methods and tools for diagram scaling.
