Product Fact Sheet
Keysight RF & Microwave Manual Step Attenuators
Key features
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.
– High reliability and exceptional repeatability reduce
downtime
– Excellent RF specications optimize test system mea-
surement capability
– Broad portfolio of attenuation and connector options
provide conguration exibility
