Time Domain
Selects the time domain representation for the active diagram area. The softkey is
enabled if a linear frequency sweep is active (see
on page 492). 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.
●
The bandfilter search functions are available for the transformed trace.
●
If marker coupling is active, then the markers in the time domain and in the fre-
quency domain are coupled with each other.
The analyzer places no restriction on the measured quantities to be transformed into
the time domain. Impedances and admittances are first converted back into the equiva-
lent S-parameter, transformed, and restored after the transformation.
