Keysight Technologies 33391C

Is a strong signal wreaking havoc on your testing equipment? Get your wavelengths under control with this RF attenuator from Keysight Technologies. It's used in RF communications systems to minimise interference and control signal levels. As it supports broadband signals from DC to 18GHz, it's a versatile piece of kit. The body is made of Noryl® modified polyphenylene oxide, which is a mechanically stable material that's resistant to stress and vibration to stand up to demanding industrial environments.

• Wide operating temperature range of 0°C to +55°C for use in harsh conditions
• Inner/outer ring coplanarity of just ±0.0178mm indicates it has excellent mechanical stability and electrical performance

• Device testing
• Radiofrequency equipment
• Research and development labs

This unit has a typical SWR (standing wave ratio) of 1.004 from DC to 2GHz. From 2 to 18GHz, it has an SWR of 1.004 + 0.0009GHz. An SWR between 1 and 1.5 is considered efficient, as it won't cause any power distortion or loss of signal strength.
