Multi-Tone Waveform Tab
The Multi-Tone Waveform tab is used to create signals made-up of
multiple tones, either equally or arbitrarily spaced. It also allows for the
definition of a frequency interval without tones (or notch) for NPR (Noise
Power Ratio) testing. Amplitudes and phases of the individual tones can be
corrected through correction factor files defined by the user. The
Multi-Tone Waveform tab allows you to generate both RF and baseband
(I/Q Data) signals. It also provides a graphic waveform preview
functionality, which can be used to validate the location and amplitudes of
the tones in the signal before sending it to the instrument or be stored in a
file for later use. The signal’s crest factor or Peak-to-Average Power Ratio
(PAPR) is also shown. The application handles requirements and limits of
the target hardware in aspects such as maximum and minimum record
lengths, sampling rate, and record length granularity. As a result,
generation of signals designed in this tab will always be feasible through
the instrument, and they will be free of distortions such as wrap-around or
timing artifacts, even if they are generated in looped mode.
