Marking
This equipment complies with the following standards:
EMC: EN 50082-1 * EN 55011 * EN 61000-3-2 * EN 61000-3-3 * IEC 801-2 * IEC801-3 * IEC 801-4
Safety: EN61010-1
The safety standards and precautions listed below must be applied scrupulously during all phases of
use and maintenance of the unit in order to prevent damage to persons, animals and objects.
UNAOHM S.r.l. assumes no liability for any incorrect use of the instrument or any use
different than that specified.
1.1. SAFETY STANDARDS
•Power the instrument with a voltage which falls within the limits specified in the characteristics
section.
•Do not use the unit without the relative locks.
•The instrument is intended for use in covered areas. Therefore do not expose it to rain or
dripping.
•Do not use the unit in an explosive atmosphere constituted by flammable gases, vapours, smoke
and powders.
•The instrument can be used in overvoltage Category IIa and pollution grade 2.
•Do not switch on the unit immediately after moving it from a very cold room to a hot one,
in order to prevent the formation of moisture condensate.
•Do not obstruct any cooling slots and do not place the unit close to heat sources.
•Do not apply DC voltage or RF signals greater than those prescribed to the input connectors.
This symbol indicates that the instructions manual must be consulted for
additional information.
This symbol indicates parts of circuit in which dangerous voltage may be present.

1.2. PRECAUTIONS
•Do not place the unit near strong magnetic or electric fields (motors, transformers, solenoid
valves, etc.)
•One of the most frequent causes for technical support intervention is due to internal short circuits
due to foreign bodies, even very small ones, which enter the unit despite all of the precautions
taken to prevent this from happening. It is therefore recommended, especially when joining
coaxial cables, not to do this in the immediate vicinity of the unit because even very small pieces
of the mesh shielding could penetrate the unit and cause occasional short circuits which are not
easily detected by technical support engineers.
1.3. MAINTENANCE
The only interventions allowed concern battery replacement
Opening the instrument and any operations must be done exclusively by qualified personnel or by
personnel with basic electro-technical and electrical safety knowledge.
•For the units equipped with a battery remember the notes included in section 1.1.
•Use suitable measures to prevent the accumulation of electrostatic charges. Do not touch circuits
inside the unit without first applying the dedicated antistatic bracelet.
•To clean the external parts:
Use soft cloths and dampen them if necessary. Do not use aggressive liquid detergents and
avoid using hydrocarbon-based substances.
Do not allow liquids or other substances to penetrate inside the unit.
1.4. NOTES
•Do not drop the unit or subject it to strong shocks. If the instrument is transported in a vehicle,
place it on a non-rigid support in order to avoid strong vibrations.
•Before using the unit carefully read the instructions contained in this user manual.
•It is strongly recommended to regularly perform (at least annually) a periodic operational test of
the instrument, accompanied by any necessary calibration operations.

2.INTRODUCTION
The FCV300 frequency converter is an accessory that, when coupled with a Field Meter, allows
displaying frequencies between 3000 MHz and 4000 MHz in "Spectrum Analyser" mode included
the frequency range of 5G signal from 3600 MHz to 3800 MHz.
In the event of random signals (that is signals which are not present continuously), if the Field Meter
is equipped with a Max Hold function, it is possible to observe these as well; these types of signals
are otherwise impossible to measure given their temporal inconsistency.
The converted carrier will be displayed in IF SAT band, that is, in the frequency range between
1000 MHz and 2000 MHz.
The size and weight are very small while the power, between 13 ± 18 Volt, is applied directly on the
RF outlet connector through LNB remote power, supplied by the same Field Meter.

3. USING THE CONVERTER
In practical applications, it is necessary that the input band to the converter be limited as its Local
Oscillator can create flutters that may cause unwanted "interferences" which, superimposed on the
frequency spectrum, disrupt vision and substantially alter the measurements.
Therefore it is recommended that the RF cable, antenna or satellite dish dedicated to the band you
wish to convert be carefully chosen and the use of band-stop filters is recommended to increase the
rejection of unwanted signals that fall outside of the operating band.
For some signals which are discontinuous over time it is necessary to use the Max Hold function
with which some of our Field Meters are equipped.
That said, the following is the sequence of operations for using the converter.
1. Connect an antenna able to receive the desired frequencies to the RF IN converter input.
2. Connect a coaxial cable from the output of the RF OUT converter to the RF BNC input of the
Field Meter.
3. Switch on the Field Meter to Spectrum mode and activate the Max Hold function, if present.
4. Power the converter via remote power supply (LNB)
5. Move to the " SAT " frequency. With the marker, go to a displayed carrier: to obtain the starting
valve of the original input frequency it is necessary to subtract 2000.00 MHz, which is the
frequency of the Local Oscillator, from the frequency indicated by the marker.
