FUNCtion Subsystem
l
The specified period must be greater than the sum of the pulse width and the edge time. The instrument will
adjust edge time and pulse width as needed to accommodate the specified period. From the remote interface, a
"Settings conflict" error will also be generated. The edge time is minimized first, and then the width (or duty cycle)
is adjusted as shown below.
Period
≥
[Pulse Width + ((Lead Edge Time + Trail Edge Time) * 0.625)]
l
This command affects the period (and frequency) for all waveform functions (not just pulse). For example, if you
select a period using FUNCtion:PULSe:PERiod and then change the output function to sine wave, the specified
period will be used for the new function.
l
Function Limitations: If you change to a function whose minimum period exceeds the value set by this command,
the period is adjusted to the new function's minimum pulse. For example, if you set a period of 2 µs and then
change to the ramp function, the instrument adjusts the period to 5 µs (the minimum for ramps). From the
remote interface, a "Settings conflict" error will also be generated.

[SOURce[1|2]:]FUNCtion:PULSe:TRANsition:TRAiling? [{MINimum|MAXimum}]
Sets the pulse edge time on the leading, trailing, or both edges of a pulse.
Parameter
Typical Return
8.4 ns to 1 µs, limited as described below; default 10 ns
+1.000000000000000E-08
Set leading edge time to 10 ns (two methods):
FUNC:PULS:TRAN:LEADing 10 ns
FUNC:PULS:TRAN:LEADing .000000010
l
The leading edge time applies to rising edge, and represents the time from the 10% threshold to the 90% thresh-
old of the edge; the trailing edge represents the time from the 90% threshold to the 10% threshold.
l
The specified edge time must fit within the specified pulse width and period. The instrument will limit the edge time
to accommodate the specified pulse width or duty cycle. From the remote interface, a "Settings conflict" error will
also be generated.
