Features and Function
HDG2000 Series Arbitrary Waveform Generator 31
The instrument will adjust the pulse width to accommodate the specified period.
Front Panel:
SCPI:
SOURce<n>:FUNCtion:PULSe:WIDTh <seconds>|MINimum|MAXimum
SOURce<n>:FUNCtion:PULSe:WIDTh? [MINimum|MAXimum]
For example, set pulse width of the channel 1 to 5ms:
SOURce1:FUNCtion:PULSe:WIDTh 0.005
3. Pulse Duty Cycle
The pulse duty cycle is defined as follows:
Duty Cycle = 100x (Pulse Width)/Period
Pulse width is the time from the 50% threshold of a pulse's rising edge to the 50% threshold of the
next falling edge.
Pulse duty cycle: 0.01% to 99.99% (see restrictions below). The default is 50%.
The pulse duty cycle must conform to the following restrictions determined by the minimum
pulse width (Wmin). The instrument will adjust the pulse duty cycle to accommodate the
specified period. Duty is associated with pulse width, if modify it, then pulse width will be
modified automatically. Pulse duty is limited by "minimum pulse width (16 ns)" and "pulse cycle".
Pulse duty≥100 x minimum pulse width/pulse cycle
Pulse duty≤100 x (1 - 2 x minimum pulse width/pulse cycle)
