To specify the required attenuation value, replace the 'X' in the model with the attenuation value in dB.
   Example: MA-505/6N-2 specifies a 6 dB, MA-505, 2.0 GHz attenuator with type N male/female connectors
                     MA-530/20D7-2 specifies an 20 dB, MA-530, 2.0 GHz attenuator with 7/16 DIN male/female connectors.
