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.
