The 355D is a step attenuator from Agilent. Attenuators are a type of radio frequency (RF) test equipment that’s useful during RF design. When an engineer needs to reduce (attenuate) the level of an electronic signal, he or she uses an attenuator. Attenuation can protect circuit stages from receiving signal levels that are too high. RF attenuators may be fixed, switched, or variable, depending on their capabilities and applications.
Additional Features:
Frequency Range: DC to 1 GHz
Attenuation Range: 0 to 120 dB, 10 dB steps
Insertion Loss at 0 dB: 0.2 dB + 2.3 dB.GHz
Maximum SWR: 1.2 to 250 MHz, 1.3 to 500 MHz, 1.5 to 1 GHz
Repeatability Life: 0.03 dB maximum, 0.5 million cycles per section
Maximum RF Input Power: 0.5 W (average), 350 W (peak)
Connector Type: BNC female, optional Type-N female and TNC female
Attenuator sections are inserted and removed by cam-actuated microswitches which keep lead lengths short. This design minimizes stray capacitances and inductances, and keeps phase shift to a minimum. The Agilent 355D is a compact and rugged unit in which the component parts are rigidly positioned and well-shielded so that neither stray pickup nor signal leakage is a problem. It may be connected with the Agilent 355C in series to provide precision attenuation in 1 dB steps from 0 to 132 dB. Either terminal may be connected as input or output.
