The 33321A DC to 4 GHz manual step attenuator offers exceptional repeatability and reliability. The 33320 step attenuator series is the compact version for the 8494/5/6/7 bench attenuators and are configured for desigining into microwave systems and instruments. Attenuation is provided in 10 dB steps from 0 to 70 dB. Precision gold-plated leaf springs ensure long life (over 5 million cycles) and very high attenuator repeatability (typically 0.01 dB). Custom step attenuator/switch combinations are possible.
