Atec Agilent-11792A User Manual

The Agilent Technologies 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 Agilent
11793A microwave converter) and levels from
+30 dBm to –127 dBm. It accurately measures AM,
FM, and fM, including residuals and incidentals,
with a single keystroke. The 8902A measuring

receiver, with the 11793A, counts RF signals to

26.5 GHz with 10 Hz resolution and excellent long­term 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).

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.”

* Shaded text signifies measurements made with the

8902A measuring receiver using the 11793A microwave
converter and 11792A sensor module. With this config­uration, all standard 8902A specifications apply except
where changes are shown as shaded text.
