INTRODUCTION
AND
DESCRIPTION
1.
The
Model
532A/B
direct-reading
frequency
me
ters
offer
good
accuracy
over
an
entire
waveguide
band.
The
meter
consists
of
a
TE^j^i
mode
resonant
cavity
coupled
to
a
waveguide
section.
When
tuned
to
resonance,
a
fraction
of
the
power
is
absorbed,
and
consequently
there
is
a
dip
of
about
1
dB
in
the
transmitted
power.
The
frequency
at
which
this
dip
occurs
may
be
read
directly
from
the
scale.
2.
The
high-Q
resonant
cavity
is
tuned
by
a
choke
plunger.
Adjustment
of
the
plunger
is
by
means
of
a
precision
lead
screw
which
is
spring-loaded
to
pre
vent
backlash.
There
are
no
sliding
contacts.
The
base
of
the
532A/B
will
accommodate
the
shaft
insert
of
a
waveguide
stand
such
as
the
HP
Model
11540A.
INSTALLATION
3.
UNPACKING
AND
INSPECTION.
4.
The
frequency
meter
was
carefully
inspected,
mechanically
and
electrically,
prior
to
shipment.
In
spect
it
for
mechanical
damage
incurred
i
n
transit,
check
for
supplied
accessories,
and
test
electrical
performance.
If
there
is
damage
or
deficiency,
notify
the
carrier
and
the
nearest
Hewlett-
Packard
office
(HP
offices
are
listed
at
the
rear
of
this
manual).
In
the
event
of
mechanical
damage,
the
packing
materials
and
carton
should
be
held
for
carrier's
inspection.
5.
REPACKAGING
FOR
SHIPMENT.
6.
USING
ORIGINAL
PACKAGING.
The
same
con
tainers
and
materials
used
in
factory
packaging
can
be
obtained
through
the
Hewlett-Packard
sales
and
service
offices
listed
at
the
rear
of
this
manual.
7.
If
the
Model
532A/B
is
being
returned
to
Hewlett-
Packard
for
servicing,
attach
a
tag
indicating
the
type
of
service
required,
return
address,
model
number
and
full
serial
number.
Also,
mark
the
container
FRAGILE
to
assure
careful
handling.
In
any
correspon
dence
refer
to
the
instrument
by
model
number
and
full
serial
number.
8.
USING
OTHER
PACKAGING.
The
following
general
instructions
should
be
used
for
repackaging
with
com
mercially-available
materials:
a.
Wrap
the
instrument
in
heavy
paper
or
plastic.
(If
shipping
to
a
Hewlett-Packard
service
office
or
center,
attach
a
tag
indicating
the
type
of
service
re
quired,
return
address,
model
number,
and
full
serial
number.)
b.
Use
a
strong
shipping
container.
A
double-wall
carton
made
of
350
pound
test
material
is
adequate.
c.
Use
enough
shock-absorbing
material
(3-
to
4-inch
layer)
around
all
sides
of
the
instrument
to
provide
firm
cushion
and
prevent
movement
inside
the
con
tainer.
Protect
the
dial
windows
with
cardboard.
d.
Seal
the
shipping
container
securely.
e.
Mark
the
shipping
container
FRAGILE
to
assure
careful
handling.

ALIGNING
FLANGES.
10.
Be
sure
to
align
the
flanges
closely
with
connecting
equipment
when
making
the
initial
setup.
This
will
help
reduce
reflections
due
to
poor
flange
mating.
11.
PRECAUTION.
12.
Protect
flanges
from
damage.
Scoring
or
burring
of
the
mating
surfaces
may
degrade
performance.
Keep
flange
covers
on
when
frequency
meter
is
not
in
use.

SETUP.
14.
A
typical
frequency-measurir^
setup
is
indicated
in
Figure
2.
A
detector
and
meter
are
required
to
indicate
the
resonant
point.
The
attenuator
(10
dB
or
more)
prevents
a
shift
in
signal
frequency
as
the
fre
quency
meter
is
tuned
through
resonance.
The
detector-
meter
combination
can
be
either
a
bolometer
and
power
meter
such
as
an
HP
Model
431B/C
or
a
detector
and
high-gain
voltmeter
such
as
the
HP
ModeI415D.
Either
a
crystal
or
barretter
(mounted
in
a
waveguide
detector
mount
such
as
the
HP
Model
485B)
can
be
used
with
the
415D.
The
RF
source
must
be
modulated
with
a
1000
Hz
square-wave
when
the
415D
is
used
as
the
indicator.

Simplified
Swept-Frequency
Setup
20.
With
any
swept-frequency
setup,
the
frequency
at
which
the
wavemeter
is
set
is
indicated
by
an
absorp
tion
of
power
at
a
particular
frequency.
This
absorp
tion
at
a
particular
frequency
is
indicated
as
a
notch
in
the
baseline.
To
determine
that
a
notch
is
due
to
the
frequency
meter
and
not
due
to
the
device
under
test,
move
the
wavemeter
while
watching
the
notch.
If
the
notch
moves,
it
is
due
to
the
frequency
meter.
The
frequency
at
the
notch
can
be
read
by
observing
the
reading
under
the
black
vertical
line
between
the
two
horizontal
red
lines.
21.
MAINTENANCE
22.
No
maintenance
is
necessary
on
the
Model
532A/B
except
keeping
the
flange
covers
on
when
not
in
use
and
the
usual
protection
against
mechanical
damage.
Keeping
the
frequency
meter
in
a
plastic
bag
while
not
in
use
will
help
prevent
the
entrance
of
dust
and
dirt.

16.
After
the
frequency
meter
has
been
tuned
to
the
desired
indication,
the
frequency
indicated
can
be
read
by
observing
the
reading

PERFORMANCE
TEST.
24.
INTRODUCTION.
25.
Do
the
following
test
for
incoming
inspection,
troubleshooting,
or
whenever
the
performance
of
the
frequency
meter
is
suspected.
Table
2
gives
the
equip
ment
necessary
for
this
test.
Other
equipment
may
be
used
provided
it
meets
or
exceeds
the
critical
specifi
cations.
A

FREQUENCY
DIAL
CALIBRATION.
27.
To
test
the
frequency
dial
calibration
proceed
as
follows:
a.
Connect
as
shown
in
Figure
4
(3.95
to
12.4
GHz)
or
Figure
5
(12.4
to
18.0
GHz).
b.
Set
the
sweep
oscillator
for
automatic
sweep
with
100
to
200
MHz
AF
centered
on
the
lowest
frequency
in
the
band.
The
transfer
oscillator
should
be
normally
set
to
200.0000
MHz
with
an
electronic
counter
reading
of
10,000.0
kHz
for
all
measurement
frequencies
which
are
harmonics
of
200
MHz.
Refer
to
Table
4
for
fre
quencies
which
are
not
harmonics
of
200
MHz.

The

This

checks
that
the

been
selected.
If
the

of
the
532A/B
under
test
had
slipped
and
the
wrong

had
been
selected,
the
532A/B

be
calibrated
erroneously
without
any
indication
of
this
fact.
e.
Adjust
the

until
the
absorption

is
centered
exactly
on
the
beat

Read
the
frequency

exactly.
This
indication
should
be
within
the
rated
overall
accuracy
(see
Table

Repeat
on
other
frequencies.
Consult
Table

frequency
but the
20th
harmonic
is
what
is
actually
used.
Most
frequencies
needed
are
harmonics
of
200

To
measure
200

accurately
set
the
converter
to
190

giving
you
a
counter
reading
around
10,000
kHz.
If
a
200

converter
frequency
was
used
and
a
reading
of
100

obtained,
the

could
be
either
100

above
or
below
200

When
a

this

does
not
exist.
Odd

BNC-to-type
N
adapter.
h.
For
convenient
Oscilloscope
display,
adjust
Oscilloscope
VERTICAL
SENSITIVITY
and
the
Attenuators
so
that
the
difference
frequency
"birdie"
and
the
Wavemeter
notch
or
hump
are
clearly
visible.
h.
Set
K532A
to
18.0
GHz
(28.0
GHz
for
R532A)
and
adjust
Transfer
Oscillator
so
that
difference
frequency
is
centered
on
Wavemeter
notch.
i.
Read
the
Electronic
Counter.
The
K532A
should
be
within
±0.11%
(0.12%
for
R532A).
To
determine
percent
error,
subtract
200
MHz
from
counter
reading
(MHz)
and
divide
by
2.
For
example,
if
the
counter
reads
200.
220,
the
percent
error
is
0.
220
divided
by
2
or
0.11%.
j.
Repeat
above
procedure
every
200
MHz.
k.
Set
Sweep
Oscillator
to
sweep
entire
band
of
532A.
m.
Tune
532A
across
band.
The
notch
travel
across
frequency
range
should
cause
at
least
a
1
dB
dip
depth
all
the
way
across.
