£600 excl VAT £375 excl VAT

The Keysight-Agilent  8494H dc to 18 GHz programmable step attenuator offers superior performance and reliability. Attenuation is provided in 1 dB steps from 0 to 11 dB.  The Agilent 8494H precision gold-plated leaf springs ensure long life (over 5 million cycles) and very high attenuator repeatability (typically 0.01 dB). A maximum switching time of 20 ms (including contact settling) speeds automatic testing. Custom step attenuator/switch combinations are possible.

Key Features:

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
