Data transfer is made easier if external accessories are connected to the analyzer or if
the instrument is integrated into a LAN. Refer to
Chapter 3.1.11, "Connecting external
accessories" , on page 31, and Chapter 3.1.12, "Remote operation in a LAN" ,
on page 35 to obtain information about the necessary steps.
1. Activate the System – [File] > "Trace Data" softtool tab.
2. In the "Trace Data" softtool tab, select "Export" – "ASCII..." to open the "Export
Data - ASCII Files" dialog.
3. In the "Export Data - ASCII Files" dialog:
a) Select a file location ("Look in:").
b) Enter a file name ("File name:").
c) Select "Save".
The analyzer writes the data of the active trace to an ASCII file and closes the dia-
log.
4. Activate the "Print" softtool tab (System – [File] > "Print") .
5. In the "Print" softtool tab, select "Print" to print the diagram area or "To Clipboard"
to copy it to the Windows clipboard.
6. Select System – [File] > "Recall Sets" > "Save..." to open the "Save" dialog for
recall sets.
7. In the "Save" dialog:
a) Select a file location ("Look in:").
b) Enter a name for the recall set file ("File name:").
c) Select "Save".
The analyzer saves the active recall set, containing channel, stimulus and trace
settings, to a
znx
file. This recall set can be restored in a later session.
3.4.2 Reflection S-parameter measurement
In a reflection measurement, the analyzer transmits a stimulus signal to the input port
of the device under test (DUT) and measures the reflected wave. Different trace for-
mats allow you to express and display the results, depending on what you want to
learn from the data. Only one analyzer test port is required for reflection measure-
ments.
In principle, a reflection measurement involves the same steps as a transmission mea-
surement. Note the following differences:
●
The basic test setup for reflection measurements involves a single DUT and ana-
lyzer port. For instance, you can connect the input of your DUT to port 1 of the ana-
lyzer as shown below.
