  • Peak and average power measurements
  • O/E transducer capability
  • Enables the user to accurately determine upper and lower peak power levels
  • Instrument's transducer has a frequency range of 250MHz, and outputs an electrical signal which corresponds directly to the optical input waveform

The Keysight 8151A cannot be operated without an optical head. All heads carry interface adapters for fiber connectors and bare fibers.
