1.WARNINGS
Marking
This device complies with the following standards and documents:
•ELECTROMAGNETIC COMPATIBILITY (EMC):
EN55011 EN61000-3-2 EN61000-3-3 EN61000-4-2 EN61000-4-3
EN61000-4-4 EN61000-4-5 EN61000-4-8 EN61000-4-11 ENV50204
•SAFETY:
EN61010-1
ATTENTION: The safety standards and precautions listed hereafter must be scrupulously
applied during all of the instrument’s use and maintenance phases in order to prevent personal
injury and/or property damage
Note: UNAOHM S.r.l. shall bear no responsibility for any use of the instrument
which does not comply with the indications contained herein.
1.1. SAFETY STANDARDS
•The instrument must be powered with a voltage value that falls within the limits specified in the
technical characteristics.
•Do not use the device without the relative closure elements.
•The instrument is designed for use in sheltered environments. It must therefore not be exposed
to rain or steady streams of water.
•Do not use the device in any explosive environments where flammable gases, vapours, fumes
and/or powders are present.
•The instrument can be utilized under Overvoltage Category IIaand Pollution Rating 2 conditions.
•In order to prevent the formation of humidity condensation, avoid turning on the device
immediately after it has been moved from a cold environment to a warm environment.
•Keep the device away from heat sources and be careful to avoid blocking any of its cooling vents.
•For prolonged use in laboratories or at fixed workstations, it is recommended to remove the
device from its carrying case in order to allow for better heat dispersion.
•Do not connect the device to DC voltage or RF sources with output values greater than those
which are indicated.
•It is recommended to periodically inspect the carrying strap, as well as its attachments and
hooks, for any damage due to regular wear. These must be replaced as soon as any deterioration
is encountered.
•Observe the following precautions for any devices with batteries installed:
1. ) Do not short-circuit the battery: this could cause it to explode.
2. ) Do not immerse the battery in water or expose it to open flames.
3. ) Never attempt to perforate or open the battery.
4. ) If the battery needs to be replaced, use an identical battery type and dispose of the old battery
in compliance with your local regulations.
5. ) Do not connect the battery with its polarity reversed.

AP401FULL-HD_rev.09_UK 5
1.2. PRECAUTIONS
•The liquid contained within the display is toxic. If the module breaks and liquid comes
out, avoid touching it with your hands or any other parts of the body, especially the eyes
and mouth. In the event of any contact, wash immediately with soap and water.
•Avoid exposing the LCD monitor to direct sunlight or intense ultra violet radiation for long
periods of time; these will cause it to deteriorate.
•The device must be kept in a location where the temperature is greater than its minimum
storage temperature. If not, the liquid crystal could solidify, resulting in damage to the
monitor. Temperatures in excess of the maximum storage temperature must also be
avoided, as these could cause the liquid crystal to irreversibly return to it isotropic state.
•The service department is frequently called upon to intervene in the event of internal
short-circuiting. This may occur whenever any foreign objects (even extremely small
ones) are able to enter the device, despite all of the precautions taken to prevent this
from happening. When abutting coaxial cables, therefore, it is recommended to avoid
doing so in the immediate vicinity of the device, as even tiny pieces of wire from the
braided sheath could enter the unit and result in occasional short circuiting. Such issues
cannot be easily detected by technical service personnel.
1.3. MAINTENANCE
Any operations involving the opening of the device and interventions upon its internal
components must only be carried out by qualified personnel or, regardless, personnel with
basic knowledge of electronics and electrical safety.
•Disconnect the power cable before initiating any operations.
•For devices equipped with batteries, please refer to the notes in section 1.1.
•Replace the fuses with the types and values specified.
•Be careful to avoid making contact with any circuits, as these can maintain an electrical
charge even when not connected to the electrical power supply (capacitors).
•Use appropriate means to prevent the accumulation of electrostatic charges. It is
recommended to avoid touching the device's internal circuits before having put on the
appropriate antistatic wrist strap.
•In order to clean the external components:
1) Disconnect the power cable.
2) Use soft cloths. Employ non-aggressive liquid detergents, avoiding the use of
hydrocarbon-based substances.
3) Do not allow any liquids or other substances to penetrate inside the instrument.

1.4. NOTES
•A number of more or less luminous fixed pixels may be present upon the LCD display.
This is to be considered normal and coincides with the production tolerance levels of the
display’s manufacturer.
•The specified precision levels refer to the device operating at its normal temperature
(approximately 10 minutes following its activation).
•Avoid subjecting the device to strong jolts and/or falls; when transporting the instrument
upon a vehicle, be sure to place it upon a non-rigid support in order to avoid excessive
vibrations.
•Is recommended to carefully read the instructions contained within this user manual
before using the device.
•In addition to its horizontal position, the instrument can also function in a vertical
position, resting upon its base.
•The customer is advised to check the proper functionality of the instrument on a regular
basis (at least once a year), to be followed by calibration if necessary.
Worn carrying cases and/or straps should also be replaced in order to avoid accidents, as
previously described in section 1.1.
This symbol indicates the necessity to consult the instruction manual for
additional information.
This symbol indicates circuit components where high-voltage may be
present
UNAOHM S.r.l. reserves the right to modify the product described herein at any
time, for either technical or commercial purposes, as well as to adapt the product
to the legal requirements of the various countries.
For this reason, the data contained within this manual may not be up-to-date.

2.INTRODUCTION
The AP401 is a total coverage field strength meter for terrestrial, cable (CATV) and 1st IF
satellite TV bands, which offers the option of including the return channel of 5-65 MHz.
The instrument is also equipped with an optical input for measuring optical signals in fiber-
optic distribution networks.
Some of its main features include:
•Measurable RF level dynamics: from 20 to 130 dBµV in the terrestrial, CATV and SAT
range, from 40 to 130 dBµV in the HF range (5-65 MHz).
From -20 to +2 dBm (+12 dBm using the 10dB calibrated optical attenuator) for the
wave lengths of 1310nm, 1490nm, 1550nm.
•Possibility of taking a large number of measurements. In particular, in addition to classic
analogue signal levels, the instrument also provides the user with the ratio between the
video and audio carriers for terrestrial and CATV bands, the carrier/noise ratio and the
strength of the digital signals, both for terrestrial and satellite.
•An accurate analysis of digital signals. BER and MER measurements, as well as the
measurement of other important QPSK/8PSK, QAM, COFDM modulation parameters, can
be provided based on the available versions. These digital signals, if free-to-air, may be
viewed by means of the MPEG4/MPEG2 decoder.
•A 5.7” colour LCD display for viewing TV signals, spectral analyses, horizontal synch
pulses, analogue measurement bars, programming options, the frequency indication, the
channel, the level, the program, the status of the instrument and the menus.
•Frequency synthesis tuning (PLL) throughout all ranges with double frequency markers.
•Spectrum analyzer with variable selectivity and frequency span, display of the frequency
on the abscissa (X) and the amplitude on the ordinates (Y).
•Audio demodulation: AM, FM, intercarriers TV mono, audio satellite subcarriers with
frequency synthesis tuning (PLL) and variable selectivity.
•Optional noise generator.
•LNB power supply and control from 5 to 24V, 22 kHz with current consumption monitor.
•DiSEqC 0F
11.1, 1.2 and 2.0 transmitter/analyzer and SCR function.
•Data Logger with 5 groups of 50 programs each, with an acquisition capability of
approximately 1500 entries.
•Standard SCART connector.
•RS232 and USB ports for connecting to a Personal Computer.
•External power supply for connection to the mains electrical network or internal battery
pack with incorporated battery charger.
