Nwidth - HP 54501A Programming Reference Manual

NWIDth
NWIDth
command/query
The
:MEASURE:NWIDTH
command places the instrument in the
continuous
measurement mode and
starts
a
NWIDTH
measurement.
The
NWIDTH
query measures and outputs the
width of the
first negative
pulse on
screen
using the
50%
levels
with Standard
measurements
selected.
If
User Defined measurements are selected, then the measurement is
made at
the mid threshold value.
The algorithm
is:
if
the first
edge on screen
is rising
then
width
=
(time at
second rising edge
•
time at First
falling edge)
else
width
=
(time
at First rising
edge
-
time at first falling edge)
Command

seconds (exponential
-
NR3 format)
