Safety
Considerations

GENERAL
This product and related document ation must be revi ewed for familiariz ation with

safety markings and instructions before operation.
This product has been designed and tested in accordance with IEC Publication

1010, "Safety Requirements for Electronic Measuring Apparatus," and has been
supplied in a s af e condition. This ins tr uction documentati on contains information
and warnings which must be followed by the user to ensure safe operation and to
maintain the product in a safe condition.

SAFETY EARTH GROUND
A uninterruptible safety earth ground must be provided from the main power

source to the product input wiring terminals, power cord, or supplied power cord
set.

CHASSIS GROUND TERMINAL
To prevent a potential shoc k hazard, always co nnect the rear-pa nel chassis gr ound

terminal to earth ground when operating this instrument from a dc power source.
SAFETY SYMBOLS
Indicates instrument damage can occur if indicated operating limits are exceeded.

!

Indicates hazardous voltages.
Indicates earth (ground) terminal

WARNING

A WARNING note denotes a hazard. It calls attention to a procedure,
practice, or the like, which, if not correctly performed or adhered to, could
result in personal injury. Do not proceed beyond a WARNING sign until the
indicated conditions are fully understood and met.

CAUTION

A CAUTION note denotes a hazard. It calls attention to an operation procedure,
practice, or the like, which, if not correctly performed or adhered to, cou ld resu lt
in damage to or destruction of part or all of the product. Do not proceed beyond
an CAUTION note until the indicated conditions are fully unde rstood and met.

Safety Considerations for this Instrument

WARNING This product is a Safety Class I instrument (provided with a protective

earthing ground incorporated in the power cord). 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 p roduct is
likely to make the product dangerous. Intentional interruption is
prohibited..

Whenever it is likely that the protection has been impaired, the instrument
must be made inoperative and be secured against any unintended operation.

If this instrument is to be energized via an autotransformer (for voltage
reduction), make sure the common terminal is connected to the earth
terminal of the power source.

If this product is not used as specified, the protection provided by the
equipment could be impaired. This product must be used in a normal
condition (in which all means for protection are intact) only.

No operator serviceable parts in this product. Refer servicing to qualified
personnel. To prevent electrical shock, do not remove covers.

Servicing instructions are for use by qualified personnel only. To avoid
electrical shock, do not perform any servicing unless you are qualified to do
so.

The opening of covers or removal of parts is likely to expose dangerous
voltages. Disconnect the product from all voltage sources while it is being
opened.

Adjustmen ts describe d i n t h e ma nu al are perfor me d w i t h po w e r su p pl i e d t o
the instrument while protective covers are removed. Energy available at
many points may, if contacted, result in personal injury.

The power cord is connected to internal capacitors that my remain live for
5 seconds after disconnecting the plug from its power supply.

For Continued protection against fire hazard, replace the line fuse(s) only
with 250 V fuse(s) or the same current rating and type (for example, normal
blow or time delay). Do not use repaired fuses or short circuited
fuseholders.

5

CAUTION: Always use the three-prong ac power cord supplied with this product. Failure to ensure

adequate earth grounding by not using this cord may cause product damage.

This product is designed for use in Installation Category II and Pollution Degree
2 per IEC 1010 and IEC 664 respectively.

This product has autorangi ng line voltage input, be sure the supply voltage is
within the specified range.

Ventilation Requirements: When installing the product in a cabinet, the
convection into and out of the product must not be restricted. The ambient
temperature (outside the cabinet) must be less than the maximum operating

temperature of the product by 4° C for every 100 watts dissipated in the cabinet.
If the total power dissipated in the cabin et is greater than 80 0 watts, then forced
convection must be used.

Product Markings CE - the CE mark is a registered trademark of the European Community. A CE

mark accompanied by a year indicated the year the design was proven.
CSA - the CSA mark is a registered trademark of the Canadian Standards

Getting Started

This chapter will help familiarize you with fundamental Test Set operation,
including:

• Accessing screens and fields

• Making a simple measurement

• Preparation for remote operation via HP-IB

25

Chapter 1, Getting Started

Before Connecting a Radio

Before Connecting a Radio

NOTE: The RF IN/OUT port should be used for all transmitter tests when the radio is co nnected

directly to the Test Set. (All MSUT (Mobile Station Under Test) transmitter power
measurements are made through this port). Off-the-air measurements can be made using the
highly-sensitive ANT IN port.

CAUTION: Overpower Damage — Refer to the Test Set’s front panel for maximum input power level.

Exceeding this level can cause permanent instrument damage.

Other Damage — Blocking the fans’s rotation or operating the Test Set in an
environment that causes excessive heat may cause damage.

Important: If excessive temperatures are sensed on the power supply regulator
assembly, the Test Set’s power supply will shut off. After temperature has
lowered to within normal operating range, use the POWER switch to cycle power
on. Remove RF power from the RF IN/OUT connector whenever the Test Set is
off.

26

Accessing the Test Set’s Screens

CDMA and Analog Modes

The Test Set has two operating modes, analog and CDMA. In CDMA mode, the
Test Set configures its elf as a cali brate d CDMA ba se st ation. In Anal og mode, the
Test Set has AMPS, NAMPS and TACS analog cellular phone test capability.

CDMA is the default power-up mode. To enter analog mode from CDMA mode:

• press one of th e ANLG SCRNS key s, or

• select a screen from the Analog To Screen menu, or

• programmatically select an analog screen using the display (DISP) HP-IB subsystem,
or

• execute a CDMA to Analog handoff.

Chapter 1, Getting Started

Accessing the Test Set’s Screens

To enter CDMA mode from analog mode:

• press one of the CDMA SCRNS keys, or

• select a screen from the CDMA To Screen menu, or

• programmatically select a CDMA screen using the display (DISP) HP-IB subsystem.

Changing A Field’s Setting

Changing A Field’s Setting

There are several types of CRT display fields in the Test Set. This section
describes some of the different types of fields, and how they are used.

Units-of-Measure Field

Figure 2 Units-of-Measure Field

Units-of-measure fields allow selection of valid units for given measurement. See

figure 2 to see an example of a units-of-measure field.

in

To change a unit-of-measure

1. Position the cursor at the unit field on the display.

2. Press a key labeled with a different unit-of-measure (such as W).

3. If the new units are valid, the measurement valu e will be displayed in the new unit-of-

measure.
