General Information
Model 8902A
Mechanical Equipment Available
The following kits might have been ordered and received with the Measuring Receiver as options. If
they were not ordered with the original shipment and are now desired, they can be ordered from the
nearest Hewlett-Packard office using the appropriate part number.
Front-Handle Kit (Option 907) Ease of handling is increased with the front-panel handles. Order H P
part number 5061-9690 for the basic kit and 2190-0048 for lockwashers (8 required).
Rack-Flange Kit (Option 908) The Measuring Receiver can be solidly mounted
to the instrument
rack using the flange kit. Order
HP
part number 5061-9678.
Rack-Flange and Front-Handle Combination Kit (Option 909)
This is not a front-handle kit and
a rack-flange kit packaged together; it is composed of a unique part which combines both functions.
Order H P part number 5061-9684 for the basic kit and 2190-9609 for lockwashers (8 required).
Chassis Slide-Mount Kit This kit
is extremely useful when the Measuring Receiver is rack mounted.
Access to internal circuits and components or the rear panel is possible without removing the
instrument from the rack. Order H P part number 1494-0017 for 432 mm (17 in.) fixed slides. (To
order adapters for non-HP rack enclosures, use
HP
part number 1494-0023.)
Chassis-Tilt, Slide-Mount Kit This kit
is the same as the Chassis Slide Mount Kit above except it
also allows the tilting of the instrument up or down 90". Order HP part number 1494-0025 for 432 mm
(17 in.) tilting slides. To order adapters for non-HP rack enclosures, use
HP
part number 1494-0023.
1-9. DESCRIPTION OF THE MEASURING RECEIVER
The HP Model 8902A Measuring Receiver is a complete measurement system for accurately
characterizing signals in the 150 kHz to 1300 MHz frequency range.
It
combines the capabilities of four
separate instruments in its ability to measure RF power, tuned RF level, carrier frequency, modulation
and the characteristics of the demodulated audio signal (as well as those of external audio signals).
This flexibility allows you to make those measurements most commonly needed to totally characterize
a signal.
The Measuring Receiver can measure an RF signal's frequency, frequency
drift,
power level (broadband,
tuned, and off-channel), amplitude modulation (AM), frequency modulation (FM), phase modulation
(QM), and
AM
and
FM
noise components.
It
recovers the modulating signal and can measure the audio
signal's frequency and distortion.
The Measuring Receiver is fully automatic and all major measurements can be made by pushing a
single key. The Measuring Receiver's large digital display shows measurement results with excellent
resolution and is easy to read. All Measuring Receiver operations can be controlled and all measurement
results can be transferred via the Hewlett-Packard Interface Bus (HP-IB). (HP-IB is Hewlett-Packard's
implementation of
IEEE
Standard 488 and ANSI Standard MC1.l.)
Power Measurements
RF Power
The Measuring Receiver delivers the accuracy and resolution of a high-performance power meter. The
H P 8902A, with the H P 11722A Sensor Module, measures power from +30 dBm to -20 dBm at
frequencies from 100 kHz to 2.6 GHz. (Refer to Table 1-1, Specifications, for specified frequencies
limits using other power sensors. The H P 8902A also accepts all H P 8480 series power sensors for
extended measurement capability.)
