NOTIFICATION OF ALARM
TYPICAL INSTALLATION DIAGRAM 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.
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.
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-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.
