SERIES 560-7XXX AND 5400-71XXX RF DETECTORS

OPERATION AND MAINTENANCE MANUAL

1. INTRODUCTION

This manual provides descriptions and specifica
tions for ANRITSU Series 560-7XXX and
5400-71XXX RF Detectors (Figure 1). It also con
tains procedures for field replacement of detector di
odes in the model 5400-71B50 and 5400-71B75 RF
detectors andmostof the Series 560-7XXX RF detec
tors.

2. GENERAL DESCRIPTION

The ANRITSU Series 560-7XXX and 5400-71XXX
RF Detectors use zero-biased Schottky diodes and
have a measurement range of –55 dBm to +16 dBm.

The detectors are used with the Model 56100A and
562 Scalar Network Analyzers and with Series
541XXA, 540XXA, and 54XXA Scalar Measurement
Systems for making coaxial transmission loss or
gain and power measurements. The detectors are
also used with the Site Master and Cable Mate Se­ries Personal SWR/RL and Fault Location Testers
for making power measurements.

NOTE: ANRITSU was for
merly known as WILTRON

4. PRECAUTIONS FOR USE OF RF

-

DETECTORS

ANRITSU RF Detectors are high-quality, precision
laboratory instruments and should receive the same
care and respect afforded such instruments. Follow
the precautions listed below when handling or con
necting these devices. Complying with these precau
tions will guarantee longer component life and less
equipment downtime due to connector or device fail
ure. Also, such compliance will ensure that RF De
tector failures are not due to misuse or abuse—two
failure modes not covered under the ANRITSU war­ranty.

a. Beware of Destructive Pin Depth of Mating

Connectors. Based on RF components re-

turned for repair, destructive pin depth of mat­ing connectors is the major cause of failure in
the field. When an RF component connector is
mated with a connector having a destructive pin
depth, damage will usually occur to the RF com­ponent connector. A destructive pin depth is one
that is too long in respect ot the reference plane
of the connector (Figure 2, page 3).

The center pin of a precision RF component con
nector has a precision tolerance measured in
mils (1/1000 inch). The mating connectors of
various RF components may not be precision
types. Consequently, the center pins of these de
vices may not have the proper depth. The pin
depth of DUT connectors should be measured to
assure compatibility before attempting to mate
them with RF Detector connectors. An
ANRITSU Pin Depth Gauge (Figure 3, page 3),
or equivalent, can be used for this purpose.

handling. However, do not drop or otherwise
treat them roughly. Mechanical shock will sig­nificantly reduce their service life.

d. Avoid Applying Excessive Power. The Se-

ries 560-7XXX and 5400-71XXX RF Detectors
are rated at +20 dBm (100 mW) maximum input
power. Exceeding this input power level, even
for short durations, will permanently damage
their internal components.

If the measured connector is out of tolerance in
the “+” region, the center pin is too long (see Ta
ble 2). Mating under this condition will likely
damage the precision RF Detector connector. If
the test device connector measures out of toler
ance in the “–” region, the center pin is too short.
This will not cause damage, but it will result in a
poor connection and a consequent degradation
in performance.

b. Avoid Over Torquing Connectors. Over

torquing connectors is destructive; it may dam
age the connector center pin. Finger-tightis usu
ally sufficient for Type N connectors. Always use
a connector torque wrench (8 inch-pounds) when
tightening GPC-7, WSMA, K, or V type connec
tors. Never use pliers to tighten connectors.

c. Avoid Mechanical Shock. RF Detectors are

designed to withstand years of normal bench

e. Do Not Disturb Teflon Tuning Washers on

-

Connector Center Pins. The center conduc
tor of many RF component connectors contains a
small teflon tuning washer that is located near

-

the point of mating (Figure 4, page 4). This
washer compensates for minor impedance dis
continuities at the interface. Do not disturb this
washer. The location of this washer is critcal to
the performance of the RF component.

f. Keep Connectors Clean. The precise geome

-

-

try that makes possible the RF component’s high
performance can be easily disturbed by dirt or
other contamination adhering to connector in
terfaces. When not in use, keep the connectors

-

covered.
To clean the connector interfaces, use a clean

cotton swab that has been dampened with dena
tured alcohol. Figure 5, page 4 illustrates the
cleaning of male and female connectors.

NOTE

The teflon washer is shown on a GPC-7
connector. A similar washer may be installed
on any ANRITSU precision connector.

NOTE

Most cotton swabs are too large to fit
in the smaller connector types. In
these cases it is necessary to peel off
most of the cotton and then twist the
remaining cotton tight. Be sure that
the remaining cotton does not get
stuck in the connector. Cotton swabs
of the appropriate size can be pur­chased through a medi­cal-laboratory-type supply center.

The following are some important tips on clean­ing connectors:

•

Use only denatured alcohol as a cleaning sol
vent.

•

Do not use excessive amounts of alcohol as
prolonged drying of the connector may be re
quired.

•

Never put lateral pressure on the center pin
of the connector.

•

If installed, do not disturb the teflon washer
on the center conductor pin.

•

Verify that no cotton or other foreign mate
rial remains in the connector after cleaning
it.

•

If available, use compressed air to remove
foreign particles and to dry the connector.

•

After cleaning, verify that the center pin has
not been bent or damaged.

diode. To replace, proceed as follows:

1. Unfasten the four detector housing top cover
retaining screws. Remove the top cover.

2. Unplug the defective diode (Figure 6) from
the PCB subassembly and remove.

3. Set the potentiometer R1 full clockwise (max
imum resistance).

4. Connect the DMM leads between pins 1 and 2
of the RF detector cable connector (Figure 7).
Measure the resistance value, which is the
maximum resistance of R1 (approximately

40.5 KΩ is typical). Record this value; it will
hereafter be referred to as “R
