The 8494H is a 18 GHz 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 18 GHz
Attenuation range: 0 to 11 dB, 1 dB steps
Insertion loss at 0 dB: 0.6 dB + 0.09 dB/GHz
Maximum SWR: 1.5 to 8 GHz, 1.6 to 12.4 GHz, 1.9 to 18 GHz
Repeatability life: 0.03 dB maximum, 5 million cycles per section
Maximum RF input power: 1 W (average), 100 W (peak)
Connector type: choice of Type-N female, SMA female, APC-7
Programming connector: 12-pin Viking, optional 14-pin DIP
The Agilent 8494H is a used Programmable Step Attenuator that offers exceptional repeatability and reliability. Attenuation is provided in 1 dB steps from 0 to 11 dB. Precision gold-plated leaf springs ensure long life (over 5 million cycles) and very high attenuator repeatability (typically 0.01 dB). To improve measurement accuracy, NIST traceable data (SWR and attenuation) is available as Option 890. A maximum switching time of 20 ms (including contact settling) speeds automatic testing. Custom step attenuator/switch combinations are possible. The Agilent 11716A/B/C interconnect kits provide quick connection of Agilent 8494/5/6/7 1 dB and 10 dB step attenuators in series for greater dynamic range with 1 dB steps.
