The Keysight (Agilent/HP) 8902A measuring receiver delivers the accuracy and resolution of a high performance power meter at frequencies from 150 kHz to 1.3 GHz (50 MHz to 26.5 GHz with the Keysight (Agilent/HP) 11793A microwave converter) and levels from +30 dBm to -127 dBm. It accurately measures AM, FM and M, including residuals and incidentals, with a single keystroke. The Keysight (Agilent/HP) 8902A measuring receiver, with the Keysight (Agilent/HP) 11793A, counts RF signals to 26.5 GHz with 10 Hz resolution and excellent long-term frequency stability. The 8902A measuring receiver with Option 050 offers increased power measurement accuracy. This option specifies Tuned RF Level on the 8902A measuring receiver to an accuracy of +/-(0.015 dB + 0.005 dB/10 dB step).
