AGILENT 8902A MEASURING RECEIVER*
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 opera-
tion, and within the frequency ranges defined below.
Supplemental characteristics are intended to provide
additional information useful in applying the instru-
ment 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 config-
uration, all standard 8902A specifications apply except
where changes are shown as shaded text.

Resolution is increased one digit with 750 µs de-empha-

The demodulated output signal present at the
Modulation Out/Audio In connector is increased in
amplitude by a factor of 10 with 750 µs de-emphasis.

DETECTORS: +peak, – peak, ±peak/2, peak hold, average (rms
sinewave calibrated), rms.
STEREO SEPARATION (50 Hz to 15 kHz): >47 dB.
1. But not to exceed: 20 kHz rates and 40 kHz peak deviations with 750 µs de-
emphasis filter.
2. Not to exceed for stated accuracy: 50 Hz to 40 kHz rates with rms detector.
3. Peak residuals must be accounted for in peak readings.
4. With 750 µs de-emphasis and pre-display "off," distortion is not specified for
modulation outputs >4V peak. This condition can occur near maximum deviation
for a measurement range, at rates <2 kHz.
5. For optimum flatness, cables should be terminated with their characteristic
impedance.
