Example:
The :MEASURE:PWIDTH
command places the instrument in the
continuous measurement mode and
starts
the Pwidth measurement.
The
PWIDTH
query measures and outputs the
width of the first displayed
positive pulse.
Pulse
width is
measured at the
50%
voltage
level
with
Standard measurements selected and at
the mid level threshold value with
User-Defined
measurements selected.
The
algorithm for
this
measurement
is:
if
the first
edge on screen
is falling
then
width
=
(time at
second
falling
edge
-
time at
first
rising edge)
else
width
=
(time at first falling edge
-
time at
First
rising edge)
