Thank you for choosing an AWT Analyzer. The PIM-P is a high performance
instrument that allows users to make reliably, highly accurate measurements of passive
intermodulation, in systems and/or components. Our test systems are built to the highest
quality standards. We strive to provide the most reliable, state of the art test equipment
allowing our customers to have the utmost confidence in the results of their testing. To
ensure you can utilize all functions and features of this test system, we strongly
recommend you familiarize yourself with this manual prior to operating your PIM-P
Analyzer. This manual contains valuable information on the safe operation of the PIM-P
test set and a brief technical background on passive intermodulation.

SAFETY SUMMARY2

2-2
PIM-PAnalyzer User’s Manual
Copyright AWT-Global, LLC. All rights reserved.
2.1 SYMBOLS
This safety requirement symbol (located on the rear panel) has been adopted by
the International Electro-technical Commission, Document 66 (Central Office) 3,
Paragraph 5.3, which directs that an instrument be so labeled if, for the correct use
of the instrument, it is necessary to refer to the instruction manual. In this case it is
recommended that reference be made to the instruction manual when connecting the
instrument to the proper power source. Verify that the correct fuse is installed for
the power available.
The CAUTION symbol denotes a hazard. It calls attention to an operational
procedure, practice or instruction that, if not followed, could result in damage to or
destruction of part or all of the instrument and accessories. Do not proceed beyond a
CAUTION symbol until its conditions are fully understood and met.
The NOTE symbol is used to mark information which should be read. This
information may be very useful to the operation when with the subject covered in
this section.
The HINT symbol is used to identify additional comments which are outside of
the normal format of the manual, however can give the user additional information
about the subject.
The following general safety precautions must be observed during all phases of
operation and maintenance of the AWT PIM-P Passive Intermodulation Analyzer. Failure
to comply with these precautions or with specific warnings elsewhere in this manual
violates safety standards of design, manufacture, and intended use of the instrument. AWT
assumes no liability for the customer’s failure to comply with these requirements.
INSTRUMENT MUST BE GROUNDED
To minimize shock hazard, the instrument chassis and cabinet must be
connected to an electrical ground. The instrument is equipped with a three
conductor, three prong AC power cable. The power cable must either be
plugged into an approved three-contact electrical outlet or used with a
three-contact to a two-contact adapter with the (green) grounding wire
firmly connected to an electrical ground at the power outlet.
DO NOT OPERATE THE INSTRUMENT IN AN EXPLOSIVE
ATMOSPHERE
Do not operate the instrument in the presence of flammable gases or
fumes.

KEEP AWAY FROM LIVE CIRCUITS
Operating personnel must not remove instrument covers. Component
replacement and internal adjustments must be made by qualified
maintenance personnel only. Never replace components or operate the
instrument with the covers removed and the power cable connected. Even
with the power cable removed, dangerous voltages may be present.
Always remove all jewelry (rings, watches, etc.) and discharge circuits
before touching them. Never attempt internal service or adjustment of the
test system unless another person, capable of rendering first aid and
resuscitation, is present.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT
Do not substitute parts or perform any unauthorized modification of the
instrument. Return the instrument to AWT for repair to insure that the
warranty and safety features are maintained.
NON IONIZING RADIO FREQUENCY RADIATION HAZARD
This device generates Radio Frequency (RF) energy under normal
operation, and should always be operated in accordance with local and
national licensing laws. RF energy in the 700 to 1,000 MHz and 1,800 to
2,200 MHz with a total power of up to 50W Watts or +47 dBm is present
at the test port during testing. The Test Port is to be terminated into a non
radiating 50 ohm load to reduce the risk of RF exposure. Do not switch RF
Power On if Test Port is open or load is unknown.
ELECTRIC SHOCK HAZARD
The device is supplied with 100 to 240 Volt AC. Prior to AC
connection always inspect the power cord and instrument case for damage.
If damage is observed, do not use this until inspected and repaired by an
authorized AWT Service center.
2.2 DISCLAIMER
PIM-P Analyzers transmit two settable CW RF signals, with a power of up to 25W each,
to measure passive intermodulation of components and transmitting systems.
ACEWAVETECH is under no circumstances accountable for use of PIM-P analyzer not
conforming to laws and regulations of national and local authorities. Customer / user bear
the full responsibility and legal accountability to use PIM-P only in a lawful manner.

2.3 POWER REQUIREMENTS
The PIM-P Series is equipped with a switching power supply that provides automatic
operation from a 100 to 240 volt, 47 to 63 Hz, single-phase, AC power source. Maximum
power consumption is 750W / 750 VA
Caution
For bench-top use, choose a clear, uncluttered area. For field use, choose a
dust free environment. Ensure that there is at least 2" of clearance at the fan air
intake on right side vents of front panel, and the exhaust vents on the left side
vents of front panel to allow for proper air circulation.
Before powering the unit up make sure the instrument does not show
indications of exposure to extensive force like dents, torn off pieces or
loose parts in the case.
