ZVA/ZVB/ZVT Reflection Measurements
1145.1084.12 2.3 E-1
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).
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.
Refer to section Scaling Diagrams to learn more about the different
methods and tools for diagram scaling.
