1.SAFETY PRECAUTIONS AND GENERAL WARNINGS
MARK
This instrument is in conformity with the following standards and regulations:
•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
The below-indicated safety precautions and general warnings must be carefully observed during
all phases of use and maintenance of the instrument in order to prevent from damaging people,
animals and property.
UNAOHM S.r.l. assumes no responsibility for incorrect use of the instrument or
in case the specified rules are not complied with.
1.1. SAFETY PRECAUTIONS
•Supply the instrument with a voltage which complies with the limits set out in the Specifications.
•Insert into a standard socket the three-pole power cable, provided as standard and equipped
with valid electric protection ground (the instrument belongs to Class 1).
•Do not use the instrument unless completely housed with all covers.
•The instrument has been designed to be used in covered environments. Do not expose it to rain
or dripping.
•Do not use the instrument in explosive atmosphere made up of gas, vapours, fumes and
flammable dusts.
•The instrument may be used in over-voltage Category II and Pollution Degree 2.
•Do not switch on the instrument immediately after taking it from a hot to a cold environment, in
order to avoid condensation.
•Do not either obstruct possible cooling slits or place the instrument next to heat sources.
•For prolonged use in labs or fixed positions, the instrument may be removed from its carrying
case to enable a better heat dissipation.
•Do not apply to the input connectors a DC or RF voltage higher than indicated.
•It is recommended to periodically check the carrying strap, the related fasteners and spring hooks
which may be damaged by use. As soon as signs of wear appear, replace these parts.
•For instruments with battery installed on them:
1° ) Do not short-circuit the battery, since it may explode.
2° ) Do not dip the battery into water or throw it into the fire.
3° ) Do not perforate or try to open the battery.
4° ) If replacing is necessary, use an original spare and throw the old battery away into the
dedicated containers.
5° ) Do not connect the battery with reversed polarity.

1.2. GENERAL WARNINGS
•The liquid of the monitor is harmful. If the module breaks and the liquid eventually
comes out, do not touch with your hands or any part of your body, especially eyes and
mouth. In any case, wash immediately with water and soap.
•Do not expose the LCD to direct sunlight or to intense ultraviolet rays for a long time. It
might deteriorate.
•Keep the instrument in a place where the temperature is higher than the minimum
storage temperature, otherwise the liquid inside the crystal solidifies and causes damage
to the monitor. Where temperatures are higher than the maximum storage temperature,
as well, the liquid inside the crystal returns to the isotropic state and the process could
be non-reversible.
•One of the most common causes of demand for technical support are internal short-
circuits, due to even tiny outer bodies which may enter the instrument, despite all
precautions to avoid it. Therefore it is strongly recommended not to cut coaxial cables
near the instrument, since even very small pieces of wire from the shielding braid could
fall into the instrument and thus provoke occasional short-circuits, not easily-detectable
by technicians.
1.3. MAINTENANCE
Permitted interventions are only: connection or replacement of the battery and/or fuses,
and insertion of internal accessories as specified in the manual.
The opening of the instrument and possible servicing must be carried out only by qualified
personnel or by operators with basic electrotechnical and electrical safety knowledge.
•Disconnect the power-supply cable before servicing.
•For instruments with battery, please refer to paragraph 1.1.
•Replace fuses with specified value and type.
•Do not come into contact with circuits keeping electric charge, although not power-
supplied (capacitors).
•Take appropriate measures against the accumulation of electrostatic charges. Do not
touch internal circuits unless wearing the special antistatic strap.
•To clean external surfaces:
1° Remove the power-supply cable.
2° Use a soft cloth. Use non-aggressive liquid detergents and avoid hydrocarbon-based
products.
3° Make sure liquids or other substances do not penetrate into the instrument.

1.4. NOTES
•Some bright dots (pixels) may remain fixed on the LCD screen. These shall be considered
as normal and they are within the manufacturing tolerances.
•The specified tolerances refer to an instrument at normal usage temperature
(approximately 10 minutes after switching on).
•Prevent the instrument from falling and from suffering strong shocks; when the
instrument is carried on vehicles, place it onto a non-rigid support in order to avoid
strong vibrations.
•It is recommended to carefully read the instructions of this user manual before using the
instrument.
•This instrument may be used either on horizontal or on vertical position, seated on the
bottom.
•It is strongly recommended to regularly check the instrument (at least once a year) and
make it be calibrated.
Furthermore, the replacement of worn-out bags and straps is highly suggested in order
to avoid mishaps, as per paragraph 1.1.
This symbol indicates it is necessary to look through the user manual to
get supplementary information.
This symbol indicates parts of the circuits with eventual dangerous
voltage.
UNAOHM S.r.l. reserves the right to bring modifications to this product at any
moment and without notice, regardless of whether the change is of technical or
commercial nature or being implemented to comply with legal requirements of
specific countries.
Therefore, data inside this manual may be not up-to-date.

2.INTRODUCTION
The AP 301 field strength meter offers a full range of terrestrial TV, cable TV (CATV), the 1st
IF satellite bands and, as an option, the return path 5÷65 MHz.
Its outstanding features are:
•Broad dynamics of measurable level: from 20 to 130 dBµV in terrestrial, CATV and SAT
ranges, from 40 to 130 dBµV in HF range (5÷65 MHz).
•Huge quantity of possible measures. In particular, besides the traditional level of
analogue signals, the instrument provides the ratio between video and audio carriers for
terrestrial and CATV bands, the carrier/noise ratio and the power of digital signals, both
terrestrial and satellite.
•An accurate analysis of digital signals. According to the different available versions, BER,
MER and other important parameters of QPSK/8PSK, QAM, COFDM modulations can be
measured. These digital channels, if free-to-air, may be watched through the MPEG
decoder.
•Colour LCD 5.7” to display TV signals, spectrum analysis, horizontal synch pulse,
analogue measurement bars, options on OSD during programming, indication of
frequency, channel, level, program and instrument status, menu.
•Frequency-synthesis tuning (PLL) throughout all ranges with double frequency marker.
•Spectrum analyzer with variable selectivity and frequency scan, display of frequency on
the abscissas (X) and width on the ordinates (Y).
•Audio demodulation: AM, FM, intercarrier TV mono, audio satellite subcarriers with
frequency-synthesis tuning (PLL) and variable selectivity.
•Optional noise generator.
•LNB power supply and control from 5 to 24 V, 22 kHz and current-absorption monitor.
•DiSEqC 0
1transmitter/analyzer 1.1, 1.2, 2.0 and SCR function.
•Data Logger with 5 plans of 50 programs each, capability of approximately 1500
acquisitions.
•Standard SCART socket.
•RS232 and USB connection to PC.
•Mains power supply through external charger or internal-battery power supply with built-
in battery charger.
