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

Technical Specifications
Specifications describe the test set’s warranted performance
and are valid over the entire operation and environmental ranges
unless otherwise noted. All specifications are valid after a
30-minute warm up period of continuous operation, and within
the frequency ranges defined below.
Supplemental characteristics are intended to provide
additional information useful in applying the instrument by
giving typical, but non-warranted performance parameters.
These characteristics are shown in Italics and labeled as
“nominal,” “typical,” or “supplemental.”
