M8195A User Interface 2
Keysight M8195A Revision 2 – Arbitrary Waveform Generator User’s Guide 63
2.11 Multi-Tone Waveform Tab
Use this tab 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 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.
