Example:
A mathematical trace value amounts to 1 (real value); the port impedance is 50 Ω. If
"Result is Wave Quantity" is on, the analyzer assumes the trace value to be 1 V, which
is converted into a linear power of 20 mW, corresponding to approx. 13 dBm. With
"Result is Wave Quantity" off, the trace value 1 is directly converted into a logarithmic
power of 0 dBm.
Tip: See also example for CALCulate<Chn>:MATH:WUNit:STATe.
Remote command:
CALCulate<Chn>:MATH:WUNit[:STATe]
Recall... / Save...
Recalls / saves a mathematical expression from / to a trace math string file. Trace math
string files are ASCII files with the default extension *.mth and contain the mathemati-
cal expression as it is written in the "User Def Math" dialog. It is possible to change or
create math string files using a text editor.
Remote command:
CALCulate<Chn>:MATH:WUNit[:STATe]
5.5.5 Time Domain tab
The "Time Domain" tab enables and configures the time domain representation of the
measurement results.
Time domain analysis requires option R&S ZNA-K2. If this option is not installed, the
"Time Domain" and Time Gate tab tabs are hidden.
Background information
Refer to Chapter 4.7.2, "Time domain analysis", on page 247.
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).
5.5.5.1 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.
