SFP STEREO FM TO
FM RADIO PROCESSOR
Main features:
• RF input and output fully agile
87,5 to 108 MHz
• Double MPX output MPX input
(switchable) for local mpx
insertion in tunnel emergency
warning applications (see SFYRDS / SFP application note)
• Extensive measurement of
Deviation, RF, Pilot, BER and
RDS
• Supervising and alarm facilities
for RF level, Deviation, RDS,
Pilot etc.
• Alarm mode logging facilities
• Memory with 64 complete SFP
presets for easy installation
Remote controllable via IP over
SNMP and web browser
• Clock synchronised by RDS or
internal reference

CONTENT DISTRIBUTION
THE STANDARD FOR RE-BROADCASTING
AND CABLE HEAD-END
The IDC SFP, stereo FM to FM processor demodulates a FM signal to MPX and re-modulates
this to a new frequency. This enables the broadcaster or cable head-end operator to re-organize
the FM frequency spectrum without signal degradation or interfering RDS data. he SFP offers
in- and outputs for MPX, audio and external MPX control and advanced measurement of RF,
MPX deviation, pilot deviation, RDS deviation etc. For network management purposes the SFP
can be remote controlled via IP over SNMP and web browser.
Application: Tunnel Emergency Warning via FM Radio
