With the 8495B manual step attenuator, a signal attenuation of 0 to 70 dB can be set manually in 10 dB steps with a bandwidth of 0 Hz to 18 GHz. Within the frequency range up to 18 GHz, it offers very good stability and repeatability of the attenuation. This is achieved through gold-plated spring contacts, which also guarantee a long service life - over 5 million switching cycles - with a repeat accuracy of typically 0.01 dB. The UK6 option offers higher accuracy and traceability to the NIST standard (SWR (standing wave ratio) and attenuation ). Higher attenuations can be achieved by connecting several attenuators in series. The connection sets 11716A / B / C offer a quick connection to the attenuators 8494/5/6/7 which have an attenuator gradation of 1 dB or 10 dB.
