Manual Step Attenuators

Keysight manual step attenuators offer fast, precise signal-level control up to 26.5 GHz. Unmatched attenuation

repeatability of less than 0.03 dB up to 5 million cycles per section ensures low measurement uncertainty. Attenuation

range of 121 dB in 1 dB step can be achieved by cascading 2 attenuators in series.
