Broadcast Power Monitor

BPME Series

This innovative product offers users more options in how they measure, monitor and protect their
RF Broadcast transmission systems while providing dependable performance and accuracy.

While the BPME provides the usual power and VSWR monitoring, it is much more than just a ‘comfort’ meter. One of the chief factors that
sets BPME apart is the depth of its functionality. From remote monitoring via a user-friendly web interface to data logging
capabilities, the BPME gives users a range of functions designed to make their jobs easier, while protecting the health of their in­vestment.

In addition, the RF test port enables users to verify spectral compliance for applications such as IBOC or HDTV at the point in the
transmission line where it matters most! The enhanced functionality of BPME puts complete analog and digital broadcast monitor­ing at the user's fingertips through user-friendly, around-the-clock, remote access from any web-enabled device. This 24/7 access
ensures that problems are detected and dealt with easily and promptly-before they escalate into more costly situations.

Measuring RF power and system match characteristics can be made with the
BPME in any installation, regardless of the signal waveform. Complex waveforms
such as 8-VSB and COFDM, used in IBOC, DAB and HDTV systems, as well as FM,
AM and CW signals are accurately measured to ensure total power output
requirements.

HIGH-LEVEL COMBINED

Combiner/Coupler

Transmitter

Transmitter

HD Radio is combined with the analog signal at the input to the antenna. Analog
powercoupled to the digital transmitter must be considered when specifying
the BPME. The 20 dB dynamic range of the BPME will allow for easy high-level
combined installations.

INTERLEAVED ANTENNA

Transmitter

HD Radio and an analog signal can use interleaved antennas for separate but
simultaneous transmission. High isolation reduces the mutual coupling however,
analog power coupled to the digital transmitter must be considered when
specifying the BPME. With 20 dB of dynamic range, the BPME is ready to handle
this type of installation.

MULTI-STATIONS

Combiner/Coupler

Transmitter

Transmitter

Multi-station operation will have a high peak-to-average power ratio, depending
on the number of stations combined. Power meters not equipped to handle this
high ratio will display accuracy errors up to 20%. With the ability to accurately
read greater than 10 dB peak-to-average power, the BPME is your choice for
multi-station applications.
