Mean Attenuation = average attenuation over the frequency range at constant command.
Measurements at 0 dBm input power unless otherwise
Attenuation range must be specified by adding a “32 or 64” to the end of the part number (eg. GT061832)
Standard Control Interface is 8 bit. Control interface is also available in 10 bit interface. Add suffix (10) after
attenuation range suffix. Other custom options available upon request.
