T
ypically
there
is
one
pulse
p er
measuremen
t.
The
pulse
is
turned
ON
for
a
user-sp ecied
time
and
the
measuremen
t
is
made
at
some
user-sp ecied
time
relativ
e
to
the
start
of
the
pulse.
The
time
un
til
the
next
pulse
consists
rst
of
the
time
required
for
the
analyzer
to
set
up
for
the
next
measuremen
t
and
second,
if
necessary
,
w
aiting
to
satisfy
the
user-sp ecied
pulse
width
and
dut
y
cycle
limit.
In
the
frequency
domain,
when
the
analyzer
is
tuned
to
the
next
frequency
,
the
maxim
um
PRP
is
ab out
30
milliseconds.
In
the
Pulse
Prole
domain,
the
frequency
do es
not
c
hange,
making
the
maxim
um
PRP
ab out
3
milliseconds.
With
a
v
eraging,
the
PRP
can
b e
ab out
1
millisecond
during
part
of
the
measuremen
t.
Other
factors
whic
h
aect
the
system
PRP
are
calibration
t
yp e,
pulse
width,
dut
y
cycle,
and
pulse
prole
domain
stop
time.
If
the
PRP
is
con
trolled
externally
,
the
HP
8510
external
trigger
input
is
used
to
sync
hronize
the
analyzer
with
the
pulse.
