• Attenuation Range: 0 to 12 dB, 1 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 355C 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 355D in series to provide precision attenuation in 1 dB steps from 0 to 132 dB. Either terminal may be connected as input or output.
