The HP/Agilent 8477A Power Meter Calibrator is a precision instrument for calibrating power meters and crystal detectors operating across microwave and millimeter-wave frequencies. It delivers stable, traceable reference signals essential for power measurement verification in calibration labs, service centers, and R&D environments. The 8477A integrates directly with the HP 432A Power Meter system via three connection cables, enabling full-scale meter verification and tracking without external charts or supplementary instruments.
