or negative frequencies. This implies that users can type negative
numbers into the “Waveform Freq.” field. For noise, the resulting
complex signal will be a limited-bandwidth Gaussian noise with
uncorrelated positive and negative frequency components. All the other
waveform types result in the same signal being generated by both I and
Q assigned channels.
I/Q selection toggle buttons for each channel are shown when the
Generate I/Q Data check box is selected. In-Phase (I) and Quadrature
(Q) components can be independently assigned to each channel.
• Segment Number
The default segment number is 1. This option is unchangeable. The
segment number section is only kept for compatibility to M8195A AWG.
Basic Waveform Parameters Section
• Waveform Type
The following waveform types are available:
• Sine: Sinusoidal waveform. Frequency and Initial Phase parameters
can be defined for this waveform type using the corresponding
controls. If the Generate I/Q check box is selected, two sine waves
with a 90º phase difference will be assigned to the I and Q
components.
• Square_Linear: Square signal with linear transitions. Frequency,
Rise Time, Fall Time, Duty Cycle, and Initial Phase parameters can
be defined for this waveform type using the corresponding controls.
• Square_Cos: Square signal with cosine shaped transitions.
Frequency, Rise Time, Fall Time, Duty Cycle, and Initial Phase
parameters can be defined for this waveform type using the
corresponding controls.
• Triangle: Triangular waveform with linear transitions. Frequency,
Symmetry, and Initial Phase parameters can be defined for this
waveform type using the corresponding controls.
• Sinc: Sin x/x waveform. Frequency, Symmetry, Sinc Length, and
Initial Phase parameters can be defined for this waveform type using
the corresponding controls.
• Noise: Gaussian noise with limited bandwidth. Frequency, Crest
Factor, and Noise Bandwidth parameters can be defined for this
waveform type using the corresponding controls. If the Generate I/Q
check box is selected, two uncorrelated noise waveforms will be
assigned to the I and Q components.
