Press the TRACE SELECT key in the TRACE keypad 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, press START CENTER and enter the lowest frequency
you want to measure in the "Start Frequency" numeric entry bar (e.g. 5 GHz).
Note:
If you use the DATA ENTRY keys at the front panel for data entry, simply
type 5 and terminate the entry with the G/n key. Refer to section "Data Entry" to
learn more about entering numeric values and characters.
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, 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 2.3.3, "Scaling Diagrams"
on page 41 to learn more about
the different methods and tools for diagram scaling.
