Format:
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)
