Agilent / HP / Keysight 11974A

This mixer is preselected from 26.5 to 40GHz to eliminate the need for signal identification. Preselection reduces mixer overload from broadband signals and reduces the interaction of local oscillator harmonics with the device under test. Equipment operators can quickly locate true signals, and software development for automated measurements is greatly simplified. These mixers feature advanced barium-ferrite technology and come with a standalone power supply. They are particularly useful for broadband millimeter signal analysis, millimeter electromagneticinterference (EMI) measurements, and unattended monitoring of millimeter signals.
