    44The digital attenuator box contains the following key components:[[BR]]
    5      Rabbit RCM3700 micro controller[[BR]]
    6      Mini-Circuits 15542 10db attenuator[[BR]]
    7      Mini-Circuits ZX76-31R5-PP-S+ 31.5db Digital step attenuator

     6     '''Mini-Circuits 15542''' 10db attenuator[[BR]]
     7     '''Mini-Circuits ZX76-31R5-PP-S+''' 31.5db Digital step attenuator

    99The rabbit is controlled thought the web interface described in the general operations page, which will in turn adjust the level of attenuation in each one of the four digital attenuators. Each attenuator pair can be adjusted in increments of 1dB between the ranges of 40db and 101db. The attenuator pairs themselves have a range of 0db to 61db and with the addition of two 10db attenuators and the various losses from connections the resultant attenuation is approximately 40dB lower.
