6.3.1.5. Switched Attenuator 0.25Watt, 0 - 30dB (10-000701)
In many practical applications for Cell Enhancers etc., the gain in each path is found to be excessive.
Therefore, provision is made within the unit for the setting of attenuation in each path, to reduce the
gain.
Switched Attenuator 10-000701 provides attenuation from 0 to 30dB in 2 dB steps The attenuation is
simply set using the four miniature toggle switches on the top of each unit. Each switch is clearly
marked with the attenuation it provides, and the total attenuation in line is the sum of the values
switched in. They are designed to maintain an accurate 50 impedance over their operating
frequency at both input and output.
