R&S WinIQSIM2 Software Manual - Rohde & Schwarz

R&S ® WinIQSIM2
Graphical User Interface
Graphics Menu
The "Graphic" dialog consists of three main parts:
●
●
●
​Generated Waveform File
​Viewport selection
Graphics area with scaling option and cursor settings (see ​chapter 5.7.4, "Graphical
Representation of Waveforms", on page 39)
Since the behavior of these parts mostly depends on each other, the functions are
explained without a strict separation into these parts.
5.7.2 Generated Waveform File
In the group box "Generated Waveform File", information on signal duration and sample
rate is displayed.
Total Signal Duration
Displays the signal duration in seconds of the available samples within the generated
waveform file.
Remote command:
​:​GENerate:​WAVeform:​DURation?​ on page 197
Sample Rate (fc)
Dispalys the Sample Rate in [Hz], that is calculated as follow:
The Sampling Rate = Number of Symbols * Oversampling Factor.
Remote command:
​:​GENerate:​WAVeform:​SAMPles?​ on page 197
​:​GENerate:​WAVeform:​SRATe?​ on page 198
Oversampling Factor
Displays the baseband oversampling factor.
This parameter is determined by the content of the generated waveform file. To adjust
the oversampling rate, set the corresponding parameters defined within the standards.
Remote command:
​:​GENerate:​WAVeform:​OSAMpling?​ on page 197
5.7.3 Viewport
In the following, the selection of the displayed area of the waveform takes place. Information
about the total duration of the signal and the sample rate is given.
1. In the "IQ Source" field, select whether the signal is displayed before summation with
AWGN, with AWGN only, or after the summation point (noise afflicted baseband signal).
