Main Channels Horizontal parameter
The horizontal parameters control the frequency, the phase and the shape of the waveform. The set of
available parameters depends on the selected waveform.
Frequency [Hz] / Period [s]
This parameter defines the frequency or the period of the generated waveform. This parameter is
available for all the functions except DC Level and Noise.
In sweep run mode it is replaced by the Phase[deg] or Start Freq./Stop Freq.[Hz] parameters .
Touching the parameter label the format switches between Frequency and Period.
Phase [deg] / Delay [s]
It controls the initial phase of the waveform. This control is available for all function except DC Level and
Noise.
For all waveforms it is displayed as “Phase” except for the Pulse function that it is displayed as Delay [s].
Symmetry [%]
This parameter is defined only for the Ramp function. It represents the percentage of the cycle in which
the ramp function is rising.
Width [s] / Duty Cycle [%]
It defines the duration of the High-level part of the Pulse function. The width is defined as Full Width at
Half Maximum (FWHM) that means the time from the medium of the leading edge to the medium of the
trailing edge. The duty cycle is the percentage value of the width compared to the period.
Touching the label, you can change the format between the Width (absolute) and Duty Cycle.
Leading
–
Trailing Edge [s]
In the Pulse or Double Pulse function, it defines the transition time between Low level and High level for
the Leading Edge and between High level and Low level for the Trailing Edge.
Note:
The values refer to the rise and fall time between the 10% and the 90% of the pulse amplitude.
The 0% to 100% transitions will be longer than the set values anyway the graph represents the entered
value as the 0% to 100% transition time.
Note:
Using the Pulse Waveform the following constraints must be met:
-
𝐿𝑒𝑎𝑑𝑖𝑛𝑔 𝐸𝑑𝑔𝑒 + 𝑇𝑟𝑎𝑖𝑙𝑖𝑛𝑔 𝐸𝑑𝑔𝑒 < 𝑃𝑒𝑟𝑖𝑜𝑑
-
𝑊𝑖𝑑𝑡ℎ < 𝑃𝑒𝑟𝑖𝑜𝑑
