Signal Hawk Demonstration


Bird signal hawk – Applications Story.

A major user of radio communication systems situated on offshore oil platforms needed a way to ensure radios were actually transmitting. Whilst all the radios had built-in self test / monitoring features these would not always provide a clear picture of what was actually happening, for example just how good was the signal being radiated.

As already mentioned, these installations were on offshore oil rigs so getting to the radios for a quick check typically involved a helicopter flight and everything that such a journey required. So doing a quick check was not that easy or quick.

The solution was to fit rigs with a bird signal hawk rack mount spectrum analyser, plus monitor antenna. The bird signal hawk can be controlled remotely selecting the frequency of interest and the resultant spectrum plots can be sent back to base via the built-in Ethernet port.

Where there were two or more rigs situated close together a single centrally located bird signal hawk with was used. Suitable antennas ensured all the radios that needed monitoring were received OK.

The attached video clip shows the results from one of the Bird Signal Hawks. This information is available anywhere in the world and can be used to provide an instantaneous check, should you received a report of a problem, or monitored over a period of time to give an indication of long term trends.

This is just one application of how the Bird Signal Hawk can be used. With rack mount and pc formats, the bird signal hawk can be used in many different ways.

Switches, Couplers, Dividers/Combiners and RF Samplers

Switches

Bird's Coaxwitch® coaxial selector switches employ a unique, rugged and reliable design which permits positive contact, low insertion VSWR and negligible cross talk between channels. The switching mechanism is 4 1/2" of RG-87/U Teflon cable which is pulled away from the mating male n connectors and rotated to the desired switch position.


Couplers

Bird Technologies offers both Tx Rx systems and bird electronic brand couplers. Tx Rx brand, hybrid directional couplers for power division and signal distribution applications. The broad array of splits facilitates balanced signal distribution in the most comprehensive systems. Additionally, the crossband couplers allow multiband operation of tower transmission lines, reducing cost and tower loading. And last but not least Bird Electronic brand directional coaxial couplers are world renowned for their high-quailty, robust construction and conservative power ratings.


Dividers/Combiners

Bird's power dividers/signal combiners are world renowned for their high-quailty, robust construction and conservative power ratings. The use of non-magnetic materials and plating provide naturally lower intermodulation performance and safety when used in high magnetic fields such as MRI. Other configurations and frequency ranges available upon request.


RF Samplers

Signal samplers are non-directional taps for sampling RF signals from a main transmission line, with minimal effect to the power level of the signals on the main line. The sampled port can be connected to a spectrum analyzer for analysis and measurement, or connected to a low gain, distribution antenna in signal boosters systems to augment communications in buildings and tunnels. We offer a broad range of sampling levels to accommodate a wide variety of applications.
