4. Create a Waveform
Waveform Generator is a tool to create IQ waveform files. IQSTAR waveform generator helps create a modulated waveform which can be used during Modulation Measurements or I/Q Measurements.
The interface allows build complex IQ waveforms without programming skills requirements.
The Waveform Generator is a separate module accessible from the shortcut on the right
side or by expanding "Measurement" > "Hardware Control" on the left under
“Plug-ins”.
Waveform Configuration
This panel allows to define different waveform settings as Constellation, TestModel, Symbol Rate, Symbol Count, Bit Source, Oversampling, Windowing, Filtering options or Crest Factor Reduction.
Waveform Display
Click on "Preview" to build and visualize the waveform. Clicking on Graph type, you can choose to plot different waveform's FOM (Figure Of Merit), such as Spectrum, CCDF, IQ envelope, Constellation or EVM vs Time.
On the right side, the main waveform's FOM are summarized (Sample Rate, Duration, Point count, PAPR, EVM values and ACPR values).
