Agilent / HP / Keysight 85081B

This High impedance input module with a frequency range of 100kHz to 1GHz and is included with every standard Agilent 8508A vector voltmeter.

This unit is a two channel receiver that makes high frequency voltage measurements easy.

Its narrowband measuring technique gives it a sensitivity of 10V to help you measure even the smallest signal.

This unit also measures the phase between two signals so you can use it for another complete set of measurements like group delay and electrical length.

The Agilent 11570A accessory kit allows measurements in a 50ohms system using the probes of a standard Agilent 85081B.
