ValueTronics International, Inc. Fixed Attenuator 8491C

The 8491C is a 18 GHz Fixed 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: Precision attenuation Flat frequency response Low SWR over broad frequency ranges at a low price The Agilent 8491C coaxial fixed attenuator provides precision attenuation, flat frequency response, low SWR over broad frequency range at a low price. The attenuator is available in nominal attenuations of 3 dB and 6 dB, also 10 dB increments from 10 dB to 30 dB. This attenuator is swept-frequency tested to ensure they meet specifications at all frequencies. Calibration points are provided on a nameplate chart attached to each unit.
