Crest Factor Section
It is an indicator only.
It shows the estimated PAPR for the current waveform in dB. Although the
definition of the PAPR parameter is always the ratio between the peak and the
average power for a signal, results change depending on the working mode.
For the I/Q Data Generation mode, the result reflects the PAPR of the
envelope of the resulting signal while for direct generation it reflects the
overall signal. The difference between the former and the latter values is close
to +3dBs in most cases.
Preview Section
Multi-Tone Preview Toolbar
The waveform preview toolbar includes the icons that provide different
functionality to preview the waveform. For details, see Waveform Preview
Toolbar.
Compilation and Panel Control Section
Save To File…
Signals can be stored in files either in BIN (for non IQ modes) or IQBIN (for IQ
modes) formats. These files may be reused within the Import Waveform tab.
Send To Instrument
Signal will be transferred to the selected segments of the selected channels.
The previous running status for the target instrument will be preserved but
sampling rate may be modified depending on the waveform requirements.
Set Defaults
All the Multi-Tone waveform parameters are set automatically to their
corresponding default values. Entries in the Arbitrary Tone table are not
modified by this button.
Two control sections show-up for equally spaced tone definition (“Equispaced” selected
in the Tone Distribution drop-down list): “Basic Multi-Tone Waveform Parameters” and
“Notch Parameters”.
Basic Multi-Tone Waveform Parameters Section
Start Frequency
It is the frequency of the first tone. If it is set to a value higher than the one in
the Stop Frequency field, this is changed back to the previous Start
Frequency.
Stop Frequency
It is the frequency of the last tone. If it is set to a value lower than the one in
the Stop Frequency field, this is changed back to the previous Stop Frequency.
Spacing
It is an indicator only.
Spacing = (Stop Frequency – Start Frequency)/(# of Tones – 1).
# of Tones
It is the total number of tones in the Multi-Tone signal including the ones in
the notch, if any.
