INTRODUCTION
541 PRODUCT DESCRIPTION
Introduction
The 541 is Inovonics’ fourth-generation FM Modulation Monitor.
It delivers a wealth of information about the transmitted signal
in terms of the RF carrier and all subcarriers, the audio compo-
nent defining the technical quality that the listener hears, and
full decoding of RDS data and SCA audio.
The all-digital 541 combines detailed DSP signal analysis with a
menu-driven touchscreen display, plus Webserver-based total
access for remote operation, including measurements, graph-
ical data and Web-browser audio monitoring of the off-air pro-
gram.

Features
Leading features of the Inovonics 541 include:
Unexcelled off-air reception of analog-FM broadcasts with
highly-accurate displays of total-modulation and other meas-

Intuitive, menu-driven setup from the front panel, or remote
setup and operation with the built-in Webserver that may be
addressed over any IP network by computer or mobile device.
The 541 supports full SNMP remote control and monitoring.
Graphic front-panel and remote display of all level metering;
FFT spectrum analysis of IF passband, MPX baseband and pro-
gram audio; oscilloscope display of program audio and stereo
XY.
Accurate, program loudness measurement to the human-
perception ITU-R BS.1770 (‘LU’) loudness specification.
Collects and logs a history-over-time of FM and audio signal
parameters.
Analog, AES3-digital, HTTP/UDP Web-streaming and independ-
ent AoIP-streaming program audio outputs, plus an FM com-
posite/MPX baseband output.
Alarms for a range of signal faults, with tallies and SMS/text or
email message dispatches to specific individuals for various
alarm conditions. All alarms are also logged chronologically.
The BandScanner™ utility scans the FM spectrum and displays
each station with its signal level, PI code and callsign.
StationRotation™ mode enables automatic sequential monitor-
ing of multiple station presets.
Stays on-channel and retains measurement setups through
signal and power losses.
