PSA-based Measuring Receiver, N5531S
Signal Analysis
N5531S Measuring Receiver
The Agilent N5531S measuring receiver is comprised of a PSA
high-performance spectrum analyzer with Option 233 (Built-in
measuring receiver personality), a P-series precision power meter
(N1911A/12A), and an N5532A sensor module. It combines multiple
precision measurement functions into one compact, integrated
system that set the new standards for metrology grade of RF,
microwave, and millimeter-wave signal measurement up to 50 GHz.
The available key measurements include: frequency counter,
absolute RF power, TRFL, AM depth, FM deviation,
M deviation,
modulation rate, and modulation distortion. Additionally, audio
measurements are also available (with Option 107 being installed to
the PSA), which include audio frequency counter, audio level, and
audio distortion/SINAD measurements.
Metrology and Calibration Applications
The N5531S is a successor to the legacy 8902A measuring receiver
and extends the frequency coverage to 50 GHz. The N5531S offers
superior accuracy, exceedingly wide dynamic range, repeatability,
and traceability mandated by metrology and calibration labs. By
placing the receiver measurements and controls directly into the
PSA, the need for an external computer is eliminated – providing a
more compact measuring receiver system.
The built-in measuring receiver personality (Option 233)
installed in the PSA enables users to set the measurement parame-
ters and to initiate the measurement via the PSA’s front panel. One
button pressing can switch between the measuring receiver mode to
other modes, such as spectrum analysis, easily and quickly.
Measurement results are shown on the PSA’s display.
Combining with P-Series power meter’s accuracy and the
PSA’s outstanding linearity, the N5531S provides superior absolute
RF amplitude specifications to meet or exceed the most challenging
requirements for calibrating the signal sources. The excellent sensi-
tivity of the N5531S in tuned RF level (TRFL) measurements allows
the users to calibrate step attenuators with the widest dynamic
range within the demanded measurement uncertainty and speed.
As the input signal level to the measurement receiver decreas-
es, the signal-to-noise ratio (SNR) will have increasingly significant
contribution to the measurement uncertainty. Taking the SNR into
account, the N5531S provides comprehensive TRFL level accuracy
specifications across the entire measurement range, which offers
realistic confidence for your measurement results.
• Absolute RF power: Accuracy of a modern digital power meter
combined with a specially designed sensor module using 848x
thermal-couple power sensor
• Tuned RF level (TRFL): measurement sensitivity of as low as
–140 dBm

with level accuracy exceeding source/attenuator
calibration requirements
• Frequency counter: 0.001 Hz frequency resolution and up to
–100 dBm sensitivity (manual mode)
• Analog modulation analysis: AM, FM, and
M to verify correct
source modulation index and distortion
• Optional audio analysis capabilities with high-impedance
audio input
• N5532A sensor modules with single input connection up to
50 GHz for accuracy, productivity, and repeatability
• Remote control through SCPI commands
The N5531S offers superb analog modulation analysis capabil-
ities that enable the users to quantify their signal sources’ modula-
tion accuracy at the metrology-grade level for the carrier signal
frequency as high as 50 GHz. The measurement parameters, such
as filter bandwidth and the number of averages, can be manually set
by pressing the PSA front panel keys to optimize the modulation
analysis. Different speed settings also allow the users for the best
compromise between the measurement speed and accuracy.
The optional audio analysis capability of the N5531S (PSA
Option 107), based on the latest digital signal processing technolo-
gies, provides ideal tool to characterize audio signals. A large set of
preconditioning filters, including the CCITT filter (PSA Option 23B),
helps users to achieve the best possible audio analysis and to mea-
sure their audio signals against the regulations.
