To Set Parameters for Pulse
To output a pulse, users need to set the “Pulse Width/Duty Cycle”, “Leading edge”,
“Trailing edge”, “Delay” and “Recover Delay” in addition to the basic parameters
(such as 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.
Pulse Width range is limited by the “Minimum Pulse Width” and the “Pulse
Period” (for the ranges of “Minumum 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 period.
