Chapter 4 Remote Interface Reference
Pulse Configuration Commands

• The specified pulse duty cycle may affect the edge time. The edge time
is adjusted first, and then the duty cycle to accommodate the specified
period, conforming to the following restriction. From the remote
interface, a “Data out of range” error will be generated and the edge
time and duty cycle will be limited as described.
Duty Cycle > 100 X (1.6 X Edge Time) ÷ Period
and
Duty Cycle < 100 X (1 – (1.6 X Edge Time) ÷ Period)
Note:
This command is affected by the FUNC:PULS:HOLD command,
which determines the value to be held constant as the period is adjusted:
the specified
pulse width
value, or the specified
pulse duty cycle
value.
See the FUNC:PULS:HOLD command for further information.
FUNCtion:PULSe:TRANsition {<
seconds
>| MINimum | MAXimum }
FUNCtion:PULSe:TRANsition? [ MINimum | MAXimum ]
Set the edge time in seconds for both the rising and falling edges.
The edge time represents the time from the 10% threshold to the 90%
threshold of each edge. You can vary the edge time from 20 ns to 100 ns
(see restrictions below). The default edge time is 20 ns. MIN = 20 ns.
MAX = 100 ns. The
:TRAN?
query returns the edge time in seconds.
• The specified edge time must fit within the specified pulse width as
shown below. The function generator will limit the edge time as
needed to accommodate the specified pulse width or duty cycle.
From the remote interface, a “Settings Conflict” error will be generated
and the edge time will be limited as described.
Edge Time < 0.625 X Pulse Width
or in terms of duty cycle:
Edge Time < 0.625 X Period X Duty Cycle ÷ 100
