HP / Keysight / Agilent 8405A Overview
The 8405A Vector Voltmeter measures voltage vectors described by both magnitude and phase, 2 channels allows for ratio measurements. Measurement capabilities include insertion loss and group delay of passband-filters and other transmission devices, gain and phase margin of amplifiers, complex impedance of mixers, antennas, etc. in the frequency range of 1 to 1000MHz. Gain or loss in excess of 90 dB and phase measurements with 0.1º resolution over a 360º phase range are possible. Comes standard with BNC adapters only.
