RIGOL Chapter 2 Basic Waveform Output
DG4000 User's Guide
To Set the Pulse Parameters
To output a pulse, users need to set the "Width/Duty", "Leading" and "Trailing",
in addition to the basic parameters (such as the frequency, amplitude, DC offset
voltage, start phase, high level, low level and align phase) introduced above.
Pulse Width/Duty Cycle
Pulse width is defined as the time from the 50% threshold of a rising edge
amplitude to the 50% threshold of the next falling edge amplitude as shown in the
figure above.
The settable range of the pulse width is limited by the "Minimum Pulse Width" and
the "Pulse Period" (for the ranges of the "Minimum Pulse Width" and "Pulse Period",
please refer to "Signal Characteristics" in "Specifications"). The default value is
500μs.
Pulse Width ≥ Minimum Pulse Width
Pulse Width ≤ Pulse Period - Minimum Pulse Width × 2
Pulse duty cycle is defined as the percentage that the pulse width takes up in the
whole pulse period.
