●
Time domain analysis requires option R&S ZNL-K2. If this option is not installed,
the "Time Domain" and Time Gate tab tabs are hidden.
●
Since firmware version 1.30, this option is also available for the R&S ZNLE.
Background information
Refer to Chapter 9.7.1, "Time domain analysis", on page 294.
For a comparison of the different transformation types and windows, and for applica-
tion examples, please also refer to the application note 1EZ44_OE (https://www.rohde-
schwarz.com/appnote/1EZ44).
10.6.5.1 Controls on the Time Domain tab
The contents of the "Time Domain" tab are also displayed on the "Meas" softtool for
non-frequency converting DUTs.
"Low Pass Settings..." opens the Low Pass Settings dialog.
Time Domain
Selects the time domain representation for the active diagram area. The softkey is
enabled if a linear frequency sweep is active (see "Lin Freq" on page 328). The ana-
lyzer automatically quits time domain representation when a different sweep type is
selected.
The time domain results are obtained by transforming the measured frequency sweep
data into the time domain using an appropriate mathematical transformation type and
frequency window ("Impulse Response"). The sweep range and the output power for
the active channel is still displayed below the diagram; the displayed time interval is
shown in a second line:
Trace settings in time domain representation
While the time domain representation is active, the trace settings behave as follows:
●
The "Start" and "Stop" settings in the "Time Gate" tab configure the time axis.
●
All trace formats including the circular diagrams are available.
●
Limit lines can be defined like the limit lines for time sweeps.
