Waveform Tab (DVB-S2/S2X)

Menu Path: Analysis > DVB-S2/S2X Properties > Waveform tab

The Waveform tab of the DVB-S2/S2X Properties Dialog Box configures the settings needed to define the generated DVB-S2/S2X signal, predistort the waveform with the measured EQ response, add AWGN Additive White Gaussian Noise - Statistically random radio noise characterized by a wide frequency range with regards to a signal in a communications channel. and save to a file or download to any connected source/AWG.

A baseband waveform is generated based on the DVB-S2/S2X signal configuration settings. Center Frequency is controlled by the connected source using the settings in Source > Control.

For configurations with multiple component carriers (Advanced configuration mode), a single waveform is generated for the selected component carrier. If Component Carrier is set to All, the generated waveform is based on CC0. In Basic configuration mode, a single component carrier signal is generated.

For each generated waveform, you can:

1. View the time domain and spectrum of the generated waveforms with the Generated Time and Generated Spectrum traces;

2. Recall the waveform as a recording. Recall As Recording automatically recalls the current waveform as a recording and begins to play it. Even if the current measurement fails because there is no valid signal source, you can recall the waveform as a recording to do a successful measurement.

3. Save the waveform into .mat files (this is the only file format supported when downloading a waveform to signal generator);

4. Download the waveform to the currently selected (properly configured) source.

The Waveform tab configures these parameters:

• Signal Length

• Oversample Ratio

• Predistortion

• AWGN

  • AWGN Added

  • Carrier To Noise Ratio

• Recall As Recording

• Download to Source

• Save to File
