necessary to accommodate the period. From the remote interface, a “Setting
conflict” error is generated and the pulse width is adjusted.
z
The specified pulse width must be less than the difference between the
period and the edge time.
Pulse Width
≤
Period – (1.6x Edge time)
The waveform generator adjusts the edge time first, and then the width if
necessary to accommodate the period. From the remote interface, a “Data out
of range” error is generated and the pulse width is adjusted.
z
The specified pulse width must be greater than the total time of one edge:
Pulse Width
≧
1.6x Edge time
z
Among the pulse width and pulse duty cycle, the FUNC:PULS:HOLD
command determines which of them is to be held and it affects this
function when the waveform generator adjusts the period.
FUNCtion:PULSe:WIDTh? [MINimum|MAXimum ]
Query the pulse width. The pulse width in seconds will be returned.
FUNCtion:PULSe:DCYCle {<percent>| MINimum|MAXimum }
Specify the pulse duty cycle in percent. The range is from 0 percent to 100
percent. The default is 10
percent. The minimum value is approximately 0
percent and the maximum value is approximately 100 percent.
z
The definition of the pulse duty cycle is described below:
Duty Cycle = 100 x Pulse width/Period
Where the pulse width represents the time from the 50% threshold of the rising
edge of the pulse to the 50% threshold of the next falling edge.
z
The duty cycle is restricted by minimum pulse width and edge time, which
prevents you from setting exactly 0 percent or 100 percent.
z
The minimum pulse width affects the value of the specified pulse duty cycle
as below:
Duty Cycle
≧
100 x Wmin/Period
And
Duty Cycle
≤
100 x (1-Wmin/Period)
