• Waveform Frequency
Repetition rate for one cycle of the standard waveform. It is always a
positive number except when Signal Type is set to Sine and the
Generate I/Q Data check box is selected. In this case, frequency may be
negative so the resulting SSB (Single-Side Band) will be located over or
below the carrier frequency.
• Initial Phase
The phase within a normalized cycle of the standard waveform for the
first sample in the segment.
• Duty Cycle
The relative width as a percentage of the mark and the space sections
of square waves.
• Rise Time
The transition time (10%-90%) for the rising edge in square waveforms.
• Fall Time
The transition time (10%-90%) for the falling edge in square
waveforms.
• Symmetry
For both triangular and sinc waveforms, it marks the location as a
percentage of the positive highest peak within a period of the basic
signal.
• Sinc Length
The number of zero crossings in a single period for the sinc waveform
type.
• Crest Factor
The peak-to-average power ratio in dBs for Noise samples before
low-pass filtering. Actual crest factor in the final signal after filtering
will be higher.
• Noise Bandwidth
Baseband noise bandwidth for Noise waveforms. For IQ modes, noise
bandwidth around the carrier frequency will be twice this parameter.
