Initial Inspection
WARNING TO AVOID HAZARDOUS ELECTRICAL SHOCK, DO NOT
PERFORM ELECTRICAL TESTS WHEN THERE ARE SIGNS OF
SHIPPING DAMAGE TO ANY PORTION OF THE OUTER
ENCLOSURE (COVERS, PANELS, METERS).
Inspect the shipping container for damage. If the shipping container or
cushioning material is damaged, it should be kept until the contents of
the shipment have been checked for completeness and the instrument
has been checked both mechanically and electrically. Procedures for
checking electrical operation are given in Chapter 3. If the contents of
the shipment are incomplete, if there is mechanical damage or defect,
notify the nearest Hewlett-Packard Office. If the instrument does not
pass the electrical performance tests given in Chapter 3, notify the
nearest Hewlett-Packard office. If the shipping container is also
damaged, or the cushioning material shows signs of stress, notify the
carrier as well as the nearest Hewlett-Packard office. Keep the shipping
materials for the carrier’s inspection. The Hewlett-Packard office will
arrange for repair or replacement without waiting for claim settlement.

Operating Environment
Operating Environment
This instrument is designed for Indoor use only.
DO NOT operate the product in an explosive atmosphere or in the
presence of flammable gasses or fumes.
This instrument may be operated in environments within the following
limits:
Temperature: 0o C to +45o C
+5oC to +40oC for Jitter operation.
+5o C to +35o C with lid printer
Altitude up to 3050m (10,000ft)
Humidity up to 95% relative humidity to 40o C, but it should be
protected from temperature extremes which may cause
condensation.
To ensure adequate cooling do not obstruct air vents in the instrument
cabinet. Do not for example operate the instrument if it is standing on its
rear feet, as air vents may be obstructed by floor covering.
CAUTION This instrument is designed for use in Installation Category II and
Pollution Degree 2 per IEC 1010 and 644 respectively.
CAUTION VENTILATION REQUIREMENTS: When installing the instrument in a
cabinet, the convection into and out of the instrument must not be
restricted. If the total power dissipated in the cabinet is greater than 800
watts, then forced convection must be used.

Preparation for Use
Preparation for Use
WARNING FOR CONTINUED PROTECTION AGAINST FIRE HAZARD
REPLACE FUSE ONLY WITH SAME TYPE AND RATINGS (see
“Fuses” on page 2-3).
WARNING If this instrument is not used as specified, the protection
provided by the equipment could be impaired. This instrument
must be used in a normal condition only (in which all means for
protection are intact).
Power Requirements
The HP 37718A/19A Communications Performance Analyzer requires a
power source of 90 V to 132 V ac or 198 V to 264 V ac at a frequency
between 47 Hz and 63 Hz (nominal).
Total power consumption is 450 VA (maximum).
The fuse rating for the power source is given in the following Table.
Fuses
Line Voltage Fuse Rating HP Part Number
90V to 264V 5A Timed, 250V 2110-1120
Fuse Replacement
Only the ac line fuse located at the rear of the instrument may be
replaced by the operator.
WARNING ALL OTHER FUSE REPLACEMENT SHOULD ONLY BE
CARRIED OUT BY SUITABLY TRAINED SERVICE PERSONNEL
AWARE OF THE HAZARDS INVOLVED.
2-3
Installation
Preparation for Use
WARNING BEFORE REMOVING THE FUSE, THE AC LINE POWER CORD
SHOULD BE DISCONNECTED FROM THE POWER SOURCE
AND THE OTHER END DISCONNECTED FROM THE
INSTRUMENT.
WARNING ONLY USE A FUSE OF THE CORRECT RATING AS LISTED IN
“Fuses” on page 2-3. DO NOT use repaired fuses or short-circuited
fuseholders: For continued protection against fire, replace the line fuse(s)
only with fuse(s) of the same voltage and current rating and type.
The fuse is removed by inserting a suitable flat bladed tool into the slot
in the fuse cap and turning counter-clockwise. The cap and the fuse can
then be removed and the fuse changed for another of the correct rating.
The fuse rating and HP part number are listed in “Fuses” on page 2-3.
Connecting to the Power Supply
WARNING This is a Safety Class I instrument (providedwith a protective earthing ground,
incorporated in the powercord). The mains plug shall only be inserted in a
socket outlet provided with a protective earth contact. Any interruption of the
protective conductor inside or outside of the instrument is likely to make the
instrument dangerous. Intentional interruption is prohibited.
CAUTION Before switching on this instrument, make sure that the line supply voltage is in the
specified ranges. Range selection is automatic.

Installation
Preparation for Use
Power Cord
WARNING TO AVOID THE POSSIBILITY OF INJURY OR DEATH, THE
FOLLOWING PRECAUTIONS MUST BE FOLLOWED BEFORE
THE INSTRUMENT IS SWITCHED ON:-
WARNING (a) Note that the protection provided by grounding the
instrument cabinet may be lost if any power cable other than the
three-pronged type is used to couple the ac line voltage to the
instrument.
WARNING (b) If this instrument is to be energized via an auto-transformer
to reduce or increase the line voltage, make sure that the common
terminal is connected to the neutral pole of the power source.
WARNING (c) The power cable plug shall only be inserted into a socket
outlet provided with a protective ground contact. The protective
action must not be negated by the use of an extension cord
without a protective conductor (grounding).
The power cord supplied with each instrument varies with the country of
destination. The following figure illustrates the standard power plug and
cord configurations that are commonly used. The part number shown
beneath each plug is the part number of the appropriate power cord and
plug. If the appropriate power cord is not included with the instrument
notify the nearest Hewlett-Packard office and a replacement will be
provided.

Connecting to the Network
The network connectors are located on the modules at the side of the
instrument. The connections available depend on the options fitted to
your instrument.
Before Connecting, note the Warning and Caution information given.
All Connectors
CAUTION When connecting or disconnecting, ensure that you are grounded or,
make contact with the metal surface of the Mainframe with your free hand to bring
you, the module, and the mainframe to the same static potential.
Modules remain susceptible to ESD damage while the module is installed in the
Mainframe
Additional ESD information is required when servicing see “AdditionalPrecautions
for Service Engineers” on page 2-14
