※ Rotary Step attenuators can be used to adjust the power signal level by step within certain frequency range without power off, they can also be used to adjust the test system's power  level  as  inset  attenuators,  it  is  small  with  high
accuracy and high stability etc.
UCL-VA serial A1 type rotary step attenuators' average power 2W,  frequency range  from  DC-6GHz,  attenuation  value 0-90dB by 0.1dB/ 1dB/ 10dB step.
