Pulse
Repetition
P
eriod,
PRP
The
time
from
the
50
p ercen
t
p oint
on
the
rising
edge
of
one
pulse
to
the
50
p ercen
t
p oint
on
the
rising
edge
of
the
next
pulse.
F
or
in
ternal
triggering
op eration
the
system
PRP
dep ends
up on
the
instrumen
t
state.
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
relative
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.

R P
Duty
Cycle
The
ratio
of
the
time
that
the
pulse
is
ON
to
the
total
Pulse
Repetition
P
erio
d.
If
the
pulse
ON
and
OFF
times
are
equal,
the
Dut

Cycle
is
50
p ercen
t.
F
or
in

op eration,
the
maximum
dut

p ercen
t
limit
can
b e
sp ecied,
but
the
actual
dut
y
cycle
may
b e
less,
dep ending
up on
the
user-sp ecifed
pulse
width
and
the
time
it
takes
for
the
analyzer
to
set
up
for
the
next
measuremen
t.
