Flann's Rugged Rotary Attenuators - Series 113 have been developed in response to the specific requirements of major UK and European communication companies, operating national point-to-point
Microwave Radio Networks, for Fade Margin and Bit Error Rate (BER) measurements in a field test environment.
Models in the range utilise many of the components from the highly regarded precision
rotary vane Attenuators produced by the company. Each instrument features a direct reading scale calibrated in 1dB increments from 0 to 50dB. The attenuation accuracy is 0.5dB over the full waveguide
frequency band. Models with an extended attenuation range up to 60dB are available to special order.
Reliability in a field test environment is enhanced by the
splash-proof design. Two expandable securing straps
allow hands-free attenuator operation in difficult situations.
The units are optionally available housed in a fitted rugged
aluminium transportation case.
The
Attenuators can be supplied fitted with ancillary pieces of test equipment to suit specific applications. In some instances these can be accommodated within the transportation case. For example
ancillary components could include flexible waveguides, waveguide to coaxial adaptors or fixed attenuators for an extended attenuation range.
