The Agilent 85107B microwave vector network analyzer is a complete system configured with an Agilent 8510C vector network analyzer, a 50 GHz S-parameter test set, a 50 GHz synthesized sweeper, and 2.4 mm measurement accessories. Option 005 adds step attenuators and bias tees to the test set; option 007 provides high power and high dynamic range. This preconfigured system is a complete solution for characterizing the linear behavior of either active or passive networks over the 45 MHz to 50 GHz frequency range.
