AM Modulation Monitor: Off-Air Tunable | 520kHz – 1720kHz in 10kHz steps or 522kHz – 1719kHz in 9kHz steps | Alarms | LCD Metering | Passive antenna included | Full network control and monitoring.

The 525N is a third generation AM modulation monitor from Inovonics. It can accept direct power from the transmitter or operate as a precision reference receiver to provide accurate out-of-air measurements reflecting ATU, phase-phase and antenna parameters.

A proprietary phase lock synchronous detector provides precise demodulation, rejects interference and retrieves only the amplitude modulated component of HD Radio™ ‘digital hybrid’ transmissions.

The 5518 includes a full-featured RBS/RBDS generator at no additional charge. The generator supports dynamic PS. It can be controlled via the 5518 presets and an ASCII terminal server that can be connected to automation to support, for example, displaying title and artist.The built-in, defeatable ITU BS412 multiplex power controller acts on all outputs to meet even the most stringent European government regulations include a full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.A 10 MHz frequency reference input allows the stereo pilot tone frequency to be locked to GPS or another high-accuracy frequency standard. This improves the performance of single-frequency networks in areas where coverage of the transmitters overlaps.The stereo encoder’s stereo sub-channel modulator can operate in normal double sideband mode and in an experimental compatible single sideband mode (SSB/VSB) that is offered to enable users to compare and assess the two modes.Analog Fallback to Digital control that allows Silence Sense to switch the active input from Analog to Digital if silence is detected in the analog input signal but not on the digital input signal. This function works vice versa as well on both analog and digital AES input.The 5518 can delay its output by as much as 16 seconds. This delay can be used as the diversity delay in Digital Radio installations.At the transmitter side you’ll be pleased by its three separate remote control ports – GPI contact closures, RS232 serial and built-in Ethernet for TCP/IP networks. The serial and Ethernet ports are supported by the supplied 5518 PC Remote Control application. This Windows® 2000/XP/Vista/7/8/10 allows you to access all 5518 features and allows you to archive and restore presets, automation lists, and system setups (containing I/O levels, digital word lengths, GPI functional assignments, etc.)The SNMP (Simple Network Management Protocol) features allow you to monitor your Optimod’s status and to send Alarm notifications via your Optimod’s Ethernet connection to your network. API features allow custom third-party applications (including automation systems) to recall presets, view status and set the controls.

The 5518’s feature set fully exploits the processor’s DSP and computer-based control architecture. To ensure absolute accuracy, you can automatically synchronize the clock to an Internet timeserver. It has a cool-running, energy-efficient switching power supply and uses the latest dual-core DSP chip technology from Freescale Semiconductor.

SOFIA HD-Radio SiteStreamer+ : DSP-based remote monitor-receiver | Outputs: L/R Analog, AES, DANTE AoIP AES67, Streaming | Web Interface | StationRotation | Alarms | SNMP

The SOFIA 568 provides analog, AES3-digital and AoIP-streaming audio outputs. It collects histograms of signal parameters and displays HD Radio album artwork, station logos and similar visuals via the Web interface.

Multiple stations can be sequentially monitored using the programmable StationRotation feature. The SOFIA 568 includes a built-in BandScanner, a real-time clock and full SNMP functionality.
