The Keysight 350D is an accurate, wide frequency range attenuator which provides attenuation from 0 dB to a maximum of 110 dB. The 350D dissipates a maximum of 5 watts in continuous use with good accuracy from dc to 1 MHz. The 350D consists of two sections: (1) 100 dB adjustable in 10 dB-steps, and (2) 10 dB, adjustable in 1-dB steps. The two sections are additive, allowing attenuation in 1-dB or 10-dB increments over the full 110-dB range. A floating input is included which isolates the attenuator circuit ground from cabinet ground, allowing an ac input to be at a dc level.
