FMHD-1 HD Radio Modulation Monitor

Description

The Belar FMHD-1 is a state-of-the-art HD Radio monitor designed to support the needs of today’s broadcaster well into the future. The monitor decodes the HD Radio signal and analog FM signal simultaneously, displaying HD Radio status, data, time alignment, and configuration information, as well as total, pilot, L, R, L+R and L-R metering and RF spectrums.

The FMHD-1 is a two rack unit monitor with a 640 × 240 wide-viewing-angle color LCD display and rotary encoder, providing a detailed, clean and simple user interface.

The FMHD-1 supports monitoring multiple audio streams and simultaneous monitoring of four streams with the optional Decoder Expansion Board and additional decoders. The unit's 8 user-assignable analog audio outputs and 3 assignable AES-3ID outputs provide support for a wide variety of broadcast scenarios, including multicasting and Surround Sound.

In addition to an antenna input for monitoring off the air, the FMHD-1 has two high-level RF inputs for transmitter-site operation. The dual RF inputs allow monitoring at installations using two transmitters to generate the combined Analog/HD signal.

Older wideband Analog FM monitors in the field may require pre-filtering in order to remove HD Radio sidebands. The FMHD-1 provides two variable-bandwidth, high-quality filtered analog composite outputs for driving these monitors while eliminating interference.

The FMHD-1 has both RJ-45 10/100 Base-T Ethernet and USB computer interfaces. When used in conjunction with the Wizard for Windows software, the FMHD-1 can be accessed remotely with various PC graphing and logging functions available. The unit also provides 4 user-assignable relay closures and email addresses used to indicate alarm conditions.
