The Keysight 11930B limiter provides input protection for a variety of RF and microwave instrumentation. Failure mode for the limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage. The Keysight 11930B provides the same protection to spectrum analyzers and sources. At even greater power levels, failure mode for limiter is either an open circuit or a short circuit to ground, thereby protecting the instrument from damage.
The Keysight 11930B is furnished with a type-N connector. This power limiter offers low insertion loss and linear operation at low input levels while providing protection against transients or short duration overloads.
