FUNCtion:PULSe:WIDTh {<seconds>|MINimum|MAXimum}
FUNCtion:PULSe:WIDTh? [MINimum|MAXimum]
Set the pulse width in seconds. 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. You can vary the pulse width from 40 ns to 1000 seconds (see restrictions
below). The default pulse width is 100 μs. MIN = 40 ns. MAX = 999.99 seconds.
The :WIDT? query returns the pulse width in seconds.
–The minimum pulse width (Wmin) is affected by the period.
Wmin = 40 ns for period <
10 s.
Wmin = 200 ns for period > 10 s, but <
100 s.
Wmin = 2 µs for period > 100 s, but <
1000 s.
– The specified pulse width must also be less than the difference between the
period and the minimum pulse width as shown below. The function generator
will adjust the pulse edge time and then the pulse width as needed to
accommodate the specified period. From the remote interface, a “Settings
conflict” error will be generated and the pulse width will be adjusted as
described.
Pulse Width <
Period – Wmin
– The specified pulse width must be less than the difference between the period
and the edge time as shown below. The function generator will limit the pulse
edge time first, and then the pulse width as needed to accommodate the
specified period. From the remote interface, a “Data out of range” error will be
generated and the pulse width will be limited as described.
Pulse Width <
Period – (1.6 × Edge Time)
– The pulse width must also be greater than the total time of one edge as shown
below.
Pulse Width >
1.6 × Edge Time
This function is affected by the FUNC:PULS:HOLD command, which determines
the value to be held constant as the period is adjusted: the specified pulse
wid th value, or the specified pulse duty cycle value. See the FUNC:PULS:HOLD
command for further information.
