The Agilent 85082A is a 50-ohm input module with a frequency range of 300 kHz to 2 GHz. The Agilent 85082A is an optional input module for the Agilent 8508A vector voltmeter. The Agilent 8508A is a two-channel receiver that makes high frequency voltage measurements easy. Its narrowband measuring technique gives it a sensitivity of 10 µV to help you measure even the smallest signal. The Agilent 8508A also measures the phase between two signals - so you can use it for another complete set of measurements - like group delay and electrical length.
